Our main focus? YOU… and all you do with .NET.

Projects

There's a growing list of projects that are currently taking advantage of our open-source Foundation, benefitting from commercially friendly IP, copyright terms, and licenses.

Community

We work not only with Microsoft, but with the broader industry to increase exposure of .NET's capabilities. All our resources are designed to support developers and your projects, and help promote your endeavors with like-minded folks!

Non-Profit

The .NET Foundation is a 501(c)(6) non-profit organization, which was established to support an innovative, commercially friendly, open-source ecosystem around the .NET platform.

.NET Foundation sponsored

Developers meet every day, across the world, in .NET user groups. Join a group—or a few!—to swap knowledge, discover opportunities, or find your next hire.
