Nonetheless, loads of code stays closed-source, and the corporate consistently receives extra requests to open it. Considered one of them is WinUI, Home windows 11’s consumer interface framework. Whereas Microsoft will not be opening it absolutely but, the corporate shared particulars about plans for the following six months, which embody “product work and foundational modifications to help a extra open and collaborative future.”

As such, Microsoft must separate what could possibly be shared with the group and what can not.

Lots of you have got requested about actually open sourcing the repo. Whereas we’re not able to decide to a selected finish date for finishing all milestones, we’re actively working towards it. This isn’t a flip-the-switch second, it’s a deliberate course of.

• Section 4: GitHub as Heart of Gravity. GitHub turns into the first place for growth, situation monitoring, and group engagement. Inside mirrors can be phased out.

Making WinUI extra open can be an incremental course of, and you may monitor it on this board on GitHub. In the meantime, builders can contribute by sharing their suggestions, submitting clear and well-written points, and upvoting current suggestions.
