How to contribute to a C# project
Install the .NET SDK version from the README, then `dotnet build` and `dotnet test`. Most issues reproduce easily in this flow.
- Use `dotnet format` to match style before opening a PR.
- Reproduce the issue with a test first, then fix it.
- Look for `up-for-grabs` labels common across .NET repos.
