Roslyn provides open-source C# and Visual Basic compilers with rich code analysis APIs. It enables building code analysis tools with the same APIs that are used by Visual Studio.
### Language Design Discussion
We are now taking language feature discussion in other repositories:
- https://github.com/dotnet/csharplang for C# specific issues
- https://github.com/dotnet/vblang for VB-specific features
- https://github.com/dotnet/csharplang for features that affect both languages
Discussion about the transition of language design to the new repos is at https://github.com/dotnet/roslyn/issues/18002.
