Feature request: WinUI 3 and Windows App SDK Support

[JLunda]

Motivation

Thank you for your work on the windows crate! I am just learning Rust and am just curious as to the roadmap for supporting Windows App SDK and WinUI 3. I ask this because I was currently attempting to use the Windows::UI::WindowsManagement::AppWindow class from the windows crate, which is analogous to the UWP AppWindow.

Suggested development SDK's for new development have changed, however, and Windows App SDK and WinUI 3 are the latest SDK's to provide a common windowing library across all Windows frameworks, including Windows 11, Windows 10, and UWP applications. I am just curious what the roadmap for supporting WinUI 3 and Windows App SDK looks like for this Rust crate.

I see you've previously worked on a winui crate and Windows App SDK, so maybe you're already looking into this. :)

Drawbacks

Limited resources and the desire to first support older Windows applications, including those from Windows 10 development may be priority for this project.

Rationale and alternatives

In the meantime, I'll keep forging ahead with the UWP classes or switch to C++/WinRT to make use of the Windows App SDK and WinUI 3. However, I really would like to learn Rust and as I get better with the language, I will look for opportunities to maybe contribute back to this effort.

Additional context

Thank you for all that you do for Rust support for Windows!

Hi @JLunda,

There are no plans to support UWP XAML or WinUI XAML at this time.
