Independent. Innovative. And always open source.

Welcome to the .NET Foundation membership portal!

The Benefits of Membership

The .NET ecosystem is constantly evolving and growing, and we've seen incredible innovation in the last few years with more to come. If you are passionate about the .NET ecosystem, then you should consider becoming a member. The way we see it, there are two major reasons to become a member.

Opportunity to influence

As a member, you can partake in ongoing discussions, vote on the board of directors, directly help with one of the many action groups and more. By providing a forum, influential contacts, a passionate community, consolidated resources, funds, we provide a unified place where you can influence the .NET ecosystem in a variety of ways. We solve problems you care about, and we care about your opinion.

Stay up to date

By being where it happens, you get to hear the news first. Even if you decide to take on a more passive member role, you can still access the discussions and information, and stay up to date through reliable sources. The .NET Foundation is an independent organization, and we need you to maintain this independence. By involving people that are passionate about .NET, that have different backgrounds and work for diverse companies, and with independent funding, we can create a powerful organization that furthers sustainable open source, a diverse and open community, and that helps evolve this incredible ecosystem that we are very passionate about.

How to join

Any individual contributor to a .NET Foundation project can apply to become a member. Contributions may include code contributions, documentation, or other significant project contribution, including evangelism, teaching, code, organizing events, etc. If in doubt, please ask us at

Upon approval, members will be notified with information on completing their membership. Individual member dues help support our operations and activities, but are voluntary - you can set your own amount, or opt-out entirely. We don't tie an individual's payment to his or her membership rights and privileges. We don't want dues to be an obstacle for anyone who is interested in getting involved. We request members pay suggested $100 annual dues.

Each year, we'll host an election for the board of directors. Any active member can nominate for a two-year term, based on their community standing, plans to advance the.NET open source ecosystem, and past performance in case they are seeking reelection.

Each .NET Foundation member can vote in the election.

Just fill out the form to let us know how you've contributed to one or more .NET Foundation projects. Please be specific - don't just link to a project, link to individual commits, pull requests, or other individual contributions.
