dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force

Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.

This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0

//
// First: if the type is a non-nullable value type then we do not do the
// *boxing conversion* from the resource to IDisposable. Rather, we do
// a *constrained virtual call* that elides the boxing if possible.
//
// Now, you might wonder if that is legal; isn't skipping the boxing producing
// an observable difference? Because if the value type is mutable and the Dispose
// mutates it, then skipping the boxing means that we are now mutating the original,
// not the boxed copy. But this is never observable. Either (1) we have "using(R r = x){}"
// and r is out of scope after the finally, so it is not possible to observe the mutation,
// or (2) we have "using(x) {}". But that has the semantics of "using(R temp = x){}",
// so again, we are not mutating x to begin with; we're always mutating a copy. Therefore
// it doesn't matter if we skip making *a copy of the copy*.
//
// This is what the dev10 compiler does, and we do so as well.
//
// Second: if the type is a nullable value type then we can similarly elide the boxing.
// We can generate
//
// {
// ResourceType resource = expr;
// try { statement; }
// finally { if (resource.HasValue) resource.GetValueOrDefault().Dispose(); }
// }
//
// Where again we do a constrained virtual call to Dispose, rather than boxing
// the value to IDisposable.
//
// Note that this optimization is *not* what the native compiler does; in this case
// the native compiler behavior is to test for HasValue, then *box* and convert
// the boxed value to IDisposable. There's no need to do that.
//
// Third: if we have "using(x)" and x is dynamic then obviously we need not generate
// "{ dynamic temp1 = x; IDisposable temp2 = (IDisposable) temp1; ... }". Rather, we elide
// the completely unnecessary first temporary.

Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

public void TestLiftedConversionOnTopOfLifted()
{
// Here's an optimization that the dev10 compiler does not do except in some special cases.
// If we have a lifted conversion "on top" of another lifted operation, then the lifted
// conversion can be "distributed" to both branches of the underlying lifted operation.
//
// For example, suppose we have
//
// return (double?)(N1() + N2());
//
// Where N1 and N2 return int?. The dev10 compiler does this in two steps: first it
// computes the int? result of the addition, and then it converts that int? to double?
// with a lifted conversion. Basically, it generates:
//
// int? t1 = N1();
// int? t2 = N2();
// int? t3 = t1.HasValue && t2.HasValue ? new int?(t1.Value + t2.Value) : new int?();
// double? t4 = t3.HasValue ? new double?((double)t3.Value)) : new double?();
//
// But t3 is completely unnecessary here. We observe that the lifted conversion:
//
// (double?) (t1.HasValue && t2.HasValue ? new int?(t1.Value + t2.Value) : new int?())
//
// Is the same as distributing the conversion to the consequence and alternative:
//
// (t1.HasValue && t2.HasValue ? (double?)( new int?(t1.Value + t2.Value) ): (double?) ( new int?() ) )
//
// And now we can optimize the consequence and alternative down to
//
// (t1.HasValue && t2.HasValue ? new double?((double)(t1.Value + t2.Value) ): new double?() )
//
// And the int? t3 disappears entirely.
//
// This optimization has the nice property that it composes well with itself.

// For example, suppose we have
//
// return -(N1() + N2());
//
// Where N1() and N2() return int?. The dev10 compiler does this in two steps: first it
// computes the int? result of the addition, and then it does a fully lifted negation:

// int? t1 = N1();
// int? t2 = N2();
// int? t3 = t1.HasValue && t2.HasValue ? new int?(t1.Value + t2.Value) : new int?();
// return t3.HasValue ? new int?(-t3.Value)) : new int?();

// which is the same as distributing the conversion to the consequence and alternative:
//
// return (t1.HasValue && t2.HasValue ? - new int?(t1.Value + t2.Value) ): - ( new int?() ) )

// and now we can optimize the consequence and alternative down to
//
// return (t1.HasValue && t2.HasValue ? new int?(-(t1.Value + t2.Value) ): new int?() )

// If we have a lifted binary operation "on top" of a lifted operation,

// can eliminate several temporaries.
//
// For example, suppose we have
//
// return N1() * N2() + 1;
//
// Where N1() and N2() return int?. We could do this the obvious way:
//
// int? n1 = N1();
// int? n2 = N2();
// int? r = n1.HasValue && n2.HasValue ? new int?(n1.Value * n2.Value) : new int?();
// int v = 1;
// return r.HasValue ? new int?(r.Value + v)) : new int?();
//
// But r and v are both unnecessary. We could instead realize this as:
//
// int? n1 = N1();
// int? n2 = N2();
// return n1.HasValue && n2.HasValue ? new int?(n1.Value * n2.Value + 1) : new int?();
//

public void TestLiftedConversionOnTopOfLifted()
{
// Here's an optimization that the dev10 compiler does not do except in some special cases.
// If we have a lifted conversion "on top" of another lifted operation, then the lifted
// conversion can be "distributed" to both branches of the underlying lifted operation.
//
// For example, suppose we have
//
// return (double?)(N1() + N2());
//
// Where N1 and N2 return int?. The dev10 compiler does this in two steps: first it
// computes the int? result of the addition, and then it converts that int? to double?
// with a lifted conversion. Basically, it generates:
//
// int? t1 = N1();
// int? t2 = N2();
// int? t3 = t1.HasValue && t2.HasValue ? new int?(t1.Value + t2.Value) : new int?();
// double? t4 = t3.HasValue ? new double?((double)t3.Value)) : new double?();
//
// But t3 is completely unnecessary here. We observe that the lifted conversion:
//
// (double?) (t1.HasValue && t2.HasValue ? new int?(t1.Value + t2.Value) : new int?())
//
// Is the same as distributing the conversion to the consequence and alternative:
//
// (t1.HasValue && t2.HasValue ? (double?)( new int?(t1.Value + t2.Value) ): (double?) ( new int?() ) )
//
// And now we can optimize the consequence and alternative down to
//
// (t1.HasValue && t2.HasValue ? new double?((double)(t1.Value + t2.Value) ): new double?() )
//
// And the int? t3 disappears entirely.
//
// This optimization has the nice property that it composes well with itself.

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force

Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force

Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force

Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```

dotnet/roslyn | 56,135 | Merge release/dev17.0 to main |
This is an automatically generated pull request from release/dev17.0 into main.
Once all conflicts are resolved and all the tests pass, you are free to merge the pull request. 🐯
## Troubleshooting conflicts
### Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
- https://github.com/dotnet/roslyn/find/release/dev17.0
- https://github.com/dotnet/roslyn/find/main
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
### Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
``` bash
git fetch --all
git checkout merges/release/dev17.0-to-main
git reset --hard upstream/main
git merge upstream/release/dev17.0
# Fix merge conflicts
git commit
git push upstream merges/release/dev17.0-to-main --force
```
