Microsoft Open-Sources Edit, WSL, and GitHub Copilot at Build

Microsoft Expands Open-Source Offerings at Build 2025

Microsoft announced several open-source projects at its Build 2025 conference, including a new command-line text editor, enhanced developer tools, and improved Linux integration.

Edit: Streamlining Command-Line Editing

Edit, a new command-line text editor for Windows, will be available by default through the Windows Insider Program this summer. Developers can launch Edit directly within the command line by typing "edit," streamlining workflows and reducing context switching.

GitHub Copilot in VS Code: Open Source Collaboration

Microsoft is also open-sourcing GitHub Copilot in VS Code. This AI-powered coding extension will gradually integrate into the VS Code open-source repository over the coming months, fostering community contributions and expanding its capabilities.

Windows Subsystem for Linux (WSL): Empowering Linux Development on Windows

Windows Subsystem for Linux (WSL), enabling Linux environments directly on Windows, is also going open source. This empowers developers to modify the source code, tailoring WSL to their specific needs and use cases.

Microsoft's commitment to open source fosters community engagement, provides valuable feedback, and drives innovation across its product ecosystem.
