React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core. The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956

React to string comparison changing on .NET Core
The default sort order for `char` / `string` changed on .NET Core. This impacted a number of our tests which weren't explicitly using ordinal to compare strings. The fix here makes our tests run consistently across the various versions of .NET Core and .NET Framework https://github.com/dotnet/runtime/issues/43956
