What is the .NET Foundation?

An Independent Non-Profit Organization

The .NET Foundation is a 503(c).6 non-profit organization set up to support an innovative, commercially-friendly, open source ecosystem around an open source .NET platform.

.NET Foundation Projects

The .NET Foundation has a growing list of projects that benefit through this open source foundation with commercially friendly IP, copyright terms and licenses.

Supporting the .NET Developer Community

The .NET Foundation works with Microsoft and the broader industry to increase the exposure of open source projects in the .NET community and the .NET Foundation. The .NET Foundation provides access to these resources to projects and looks to promote the activities of our communities.

Why .NET?

  • Samsung is embracing .NET because it is a completely open source project.

  • ASP.NET Core is open source, that allows us to contribute back to it if we have any performance issues which Microsoft review and together we make a better product.

  • Being able to develop a vast amount of Xamarin code, most of it only once, that serves multiple platforms is a great efficiency benefit for years to come.

  • Using the same-size server, we were able to go from 1,000 requests per second per node with Node.js to 20,000 requests per second with .NET Core.
