.NET Foundation Projects

Projects—and the people behind them—are at the heart of what .NET Foundation is all about. These days, you'll find a wide variety of projects, including the .NET Compiler Platform, ASP.NET, .NET Core, and Xamarin Forms, along with the popular .NET open-source frameworks xUnit and Reactive Extensions.

Can you contribute to something already in the works? Browse our projects below to find out how to contribute!

Of course, we're always on the lookout for new open-source projects to support.
