Ecosystem
Microsoft is proud to support amazing open source projects, initiatives, foundations, and contribute to thousands of open source communities on GitHub and beyond.
Here are just a few of the ways that we're working to collectively empower every person and every organization on the planet to achieve more.
FOSS Fund
The Free and Open Source Software Fund (FOSS Fund) is a way for our employees to collectively select open source projects to receive $10,000 sponsorship awards throughout the year.
Microsoft's engineers select projects they are super passionate about. Only employees who contribute to open source projects can participate in the selection process.
ESLint
Find and fix problems in your JavaScript code.
Engineers across Microsoft love ESLint and use it as an important part of their inner dev loop. ESLint makes the JavaScript and TypeScript world more consistent and helps everyone be more efficient in delivering value.
eslint.orgrust-analyzer
rust-analyzer is an implementation of Language Server Protocol for the Rust programming language. It provides features like completion and goto definition for many code editors, including VS Code, Emacs and Vim.
This sponsorship is currently being processed. The selection process completed in July 2020.
There is a large Rust fanbase at Microsoft, and engineers using Rust find themselves using rust-analyzer every day. It's often paired with Visual Studio Code by productive Rust engineers.
rust-analyzer.github.ioImageSharp
A modern, cross-platform, 2D Graphics library for .NET.
This sponsorship is currently being processed. The selection process completed in August 2020.
SixLabors/ImageSharp
Network Time Protocol
(NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.
This sponsorship is currently being processed. The selection process completed in August 2020.

Whether an official contribution as part of a team's business goals, an after-hours project in robotics and hackathons, or contributions to non-profits and communities, our employees are always involved.
NOTE: This data represents contributions on GitHub that some of our employees have opted in to sharing. Microsoft does not endorse any particular contribution here, as this list will include everything from hobbyist work through official upstream contributions.
Foundations & Initiatives
Microsoft is proud to participate, partner, and sponsor many amazing initiatives to better the open source ecosystem.
Alliance for Open Media
Next Generation, Open-Source Digital Media Technology for Everyone
Alliance for Open MediaThe Confidential Computing Consortium (CCC) brings together hardware vendors, cloud providers, and software developers to accelerate the adoption of Trusted Execution Environment (TEE) technologies and standards.
About CCCClearlyDefined is on a mission to help FOSS projects thrive by being, well, clearly defined. Lack of clarity around licenses and security vulnerabilities reduces engagement — that means fewer users, fewer contributors and a smaller community.
About ClearlyDefinedThe Cloud Native Computing Foundation (CNCF) hosts critical components of the global technology infrastructure. CNCF brings together the world’s top developers, end users, and vendors and runs the largest open source developer conferences.
Visit CNCFDIF is an engineering-driven organization focused on developing the foundational elements necessary to establish an open ecosystem for decentralized identity and ensure interop between all participants.
About DIFThe .NET Foundation is an independent, non-profit organization established to support an innovative, commercially friendly, open-source ecosystem around the .NET platform.
