The .NET Foundation is an independent organization, incorporated on March 31, 2014, by Microsoft, to improve open-source software development and collaboration around the .NET Framework. It was launched at the annual Build 2014 conference held by Microsoft. The foundation is license-agnostic, and projects that come to the foundation are free to choose any open-source license, as defined by the Open Source Initiative (OSI). The foundation uses GitHub to host the open-source projects it manages.
The foundation began with twenty-four projects under its stewardship including .NET Compiler Platform ("Roslyn") and the ASP.NET family of open-source projects, both open-sourced by Microsoft Open Technologies, Inc. (MS Open Tech). Xamarin contributed six of its projects including the open source email libraries MimeKit and MailKit. As of July 2015[update], it is the steward of thirty-six projects, including: .NET Core, Entity Framework (EF), Managed Extensibility Framework (MEF), Umbraco, MSBuild, NuGet, Orchard CMS and WorldWide Telescope. Many of these projects are also listed under Outercurve Foundation project galleries.
