Microsoft Moves Mainline WinUI Development to GitHub

Microsoft has completed the planned migration of WinUI to open-source development, moving its mainline development process to GitHub.

Developers can now create branches, submit pull requests, and perform code reviews directly through the public repository.

Microsoft is testing WinUI pull requests before opening contributions

Microsoft developers currently submit all pull requests while the company tests its development and review infrastructure.

The temporary restriction gives Microsoft time to verify that its end-to-end workflow works correctly before allowing developers outside the company to contribute code.

Community pull requests will arrive at a later stage, although Microsoft has not announced when it will open submissions.

WinUI open-source work will continue

Completing the four-stage migration plan does not mean Microsoft has finished its open-source work around WinUI.

The company plans to pursue additional open-source goals and publish new milestones after it finalizes them. One of those milestones will focus on enabling community members to submit pull requests.

Opening WinUI development further could give Windows developers more influence over the framework and potentially encourage broader adoption for native Windows 11 apps.

Microsoft has also been updating more Windows tools with modern interfaces. The company recently started modernizing the Windows 11 print management tool.

At the same time, Microsoft continues investing in WebView2 rather than moving exclusively toward WinUI. The company recently announced that WebView2 is switching to a two-week release cycle.
