The .NET Foundation Joins the Open Source Initiative’s Affiliate Program

PALO ALTO, Calif., October 20th, 2020 — The Open Source Initiative® (OSI), the international authority in open source licensing, is excited to announce the affiliate membership of the .NET Foundation, the world’s biggest repository of .NET projects and resources. Welcoming the .NET Foundation to the OSI Affiliate program further solidifies the .NET community’s commitment to open source and highlights the open source movement’s continued success across many different platforms.

Executive Director of the .NET Foundation Claire Novotny says, “We’re excited to join the OSI and look forward to working together to support open source. The .NET Foundation is very interested in building on our existing commitment to interoperability and developer education with other members of the OSI Affiliate community.”

The .NET Foundation was founded in 2014 and is dedicated to growing the open source ecosystem built around the .NET development platform. The Foundation started with twenty-four projects in its care, most donated by Microsoft. These days, you’ll find over one hundred active projects, including the .NET Compiler Platform, C#, ASP.NET, .NET Core, and Xamarin, along with many popular .NET open-source frameworks like xUnit, ImageSharp, Polly, and Reactive Extensions. The .NET Foundation promotes the broad spectrum of software available to .NET developers through, GitHub, and other venues and supports the community through advocacy, education, marketing and administrative support.

Josh Simmons, Board Chair of the Open Source Initiative adds, “I’d personally like to enthusiastically welcome the .NET Foundation to the OSI’s community of open source practitioners. Organizations that support developers by fostering growth, learning and shared resources are the future of open source. I think it’s safe to say that we’re looking forward to learning from each other.”

The OSI Affiliate Member Program, available at no-cost, allows non-profit organizations to join and support the OSI’s work to promote and protect open source software. Affiliate members participate directly in the direction and development of the OSI through board elections and incubator projects that support software freedom. Membership provides a forum where open source leaders, businesses, and communities engage through member-driven initiatives to increase awareness and adoption of open source software.
