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.
If you want to suggest a new feature for the C# or Visual Basic languages go here:
- dotnet/csharplang for C# specific issues
- dotnet/vblang for VB-specific features
- dotnet/csharplang for features that affect both languages
Some of the best ways to contribute are to try things out, file bugs, and join in design conversations.
A great way to get started is to ask some questions!
- Start with a question on discussions
- You can also join in on the design discussions on gitter or discord
- First read this guide: How to Contribute
- Building, testing and debugging the sources
- Top Bugs
