Independent. Innovative. And always open source.

You've found the heartbeat of .NET—where projects and communities come together to get things done in our open-source world. Share your skills for the greater good. Meet in person, get involved virtually, and stay on top of the latest news, meetups, and events.

Active Projects

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


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.


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!


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.
