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.
``` 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
```

- 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. 🐯

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
```

// a null constant argument, so that the null literal gets "LiteralConstant" whereas every other

// a null constant argument, so that the null literal gets "LiteralConstant" whereas every other
// constant gets "LiteralConstant | UseCompileTimeType". Because obviously UseCompileTimeType is
// wrong for the null literal.
// We care, because we want to prevent this from working:
//
// const C x = null;
// class C { public void M(SomeUnrelatedReferenceType x) { } }

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

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
```

- 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

| ./docs/features/local-functions.work.md | Local Function Status
=====================
This is a checklist for current and outstanding work on the local functions
feature, as spec'd in [local-functions.md](./local-functions.md).
--------------------
Known issues
============
Compiler:
- [ ] Parser builds nodes for local functions when feature not enabled (#9940)
- [ ] Compiler crash: base call to state machine method, in state machine
method (#9872)
- [ ] Need custom warning for unused local function (#9661)
- [ ] Generate quick action does not offer to generate local (#9352)
- [ ] Parser ambiguity research (#10388)
- [ ] Dynamic support (#10389)
- [ ] Referring to local function in expression tree (#10390)
- [ ] Resolve definite assignment rules (#10391)
- [ ] Remove support for `var` return type (#10392)
- [ ] Update error messages (#10393)
IDE:
- [ ] Some selections around local functions fail extract method refactoring
[ ] (#8719)
- [ ] Extracting local function passed to an Action introduces compiler error
[ ] (#8718)
- [ ] Ctrl+. on a delegate invocation crashes VS (via Extract method) (#8717)
- [ ] Inline temp introduces compiler error (#8716)
- [ ] Call hierarchy search never terminates on local functions (#8654)
- [ ] Nav bar doesn't support local functions (#8648)
- [ ] No outlining for local functions (#8647)
- [ ] Squiggles all over the place when using an unsupported modifier (#8645)
- [ ] Peek definition errors out on local function (#8644)
- [ ] Void keyword not recommended while declaring local function (#8616)
- [ ] Change signature doesn't update the signature of the local function (#8539)
Feature Completeness Progress
=============================
- [x] N-level nested local functions
- [x] Capture
- Works alongside lambdas and behaves very similarly in fallback cases
- Has zero-allocation closures (struct frames by ref) on functions never
converted to a delegate and are not an iterator/async
- [x] Standard parameter features
- params
- ref/out
- named/optional
- [x] Visibility
- May revisit design (currently shadows, may do overloads)
- [x] Generics
- Nongeneric local functions in generic methods (same as lambdas).
- Generic local functions in nongeneric methods.
- Generic local functions in generic methods.
- Arbitrary nesting of generic local functions.
- Generic local functions with constraints.
- [x] Inferred return type
- [x] Iterators
- [x] Async

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
```
