No, it died on Windows 11. On Windows 10 everything MSFT developed was UWP. They were basically banned to use anything else. The only thing that used old frameworks, were... old "legacy" components.And the old legacy components barely had updates because they avoid to touch. WinUI (in part) was even born because of this. They already had internal XAML controls (DEPControls) for all their apps, and they decided to open-source and named WinUI. And then later they also wanted to open-source the UWP XAML stack and decouple from Windows updates, and that became WinUI 3.0. Even on 11 launch, there was an attempt to continue with this effort, but well, it's Microsoft... they rewrote taskbar to be UWP (not WInUI 3!), because well, WinUI 3 was (and is) worse than UWP. On other apps, they didn't wanted to rewrite from scratch, because then you would break compat (File Explorer Shell extensions, context menu... etc), so they had a great idea to just mix old UI with WinUI! So you have WinUI on Notepad, File Explorer, Paint, etc, but not in the entire of it. So they were trying to make things more consistent (and WinUI), and it only got worse because mixing the two added too much complexity, WinUI 3 is slower than UWP, etc. So they started going web. Also because of budget reasons.
