Same for me. Syntax Highlighting just doesnt work correctly after a yield statement:

[JoeRobich]

@AnmolSinha1201 @mircmo We recommend setting csharp.semanticHighlighting.Enabled to true in VS Code settings. This appears to be an issue with the C# textmate grammar which is in this repo https://github.com/dotnet/csharp-tmLanguage

[mircmo]

Thanks @JoeRobich it works with that setting :) Just out of curiosity, is there any reason why you would want to have this setting disabled to begin with?

[JoeRobich]

@mircmo The implementation is still considered experimental and hasn't had a lot of work put in for performance. Also, there are some highlighting issues in the diff view.

[JoeRobich]

Closing as semantic highlighting is available as well as many improvements have been made to the textmate grammar.
