.NET Compiler Platform

Roslyn is the open-source implementation of both the C and Visual Basic compilers with an API surface for building code analysis tools. All work on the C and Visual Basic compiler happens directly on GitHub. Both core team members and external contributors send pull requests which go through the same review process. If you are interested in fixing issues and contributing directly to the code base, a great way to get started is to ask some questions on GitHub Discussions! Then check out our contributing guide which covers the following: Coding guidelines The development workflow, including debugging and running tests Submitting pull requests Finding a bug to fix in the IDE or Compiler Finding a feature to implement in the IDE or Compiler Roslyn API suggestions should go through the API review process The Roslyn community can be found on GitHub Discussions, where you can ask questions, voice ideas, and share your projects. To chat with other community members, you can join the Roslyn channel on the CSharp Community Discord.
