While the backends are unified, MS still do refuses to fix the UI framework. They instead have yet another version of the post WPF scrambled egg UI framework. AKA WinUI3.

the native grumpy old people like me will continue to use Windows forms or WPF or MFC,ATL,Win32.

The masochists will try to use the open-source silverlight replacement. Moonlight?

The futurists will use Avalonia. Maybe SAFE stack MVU via Fable?

The Microsoft contractors will use WinUI3.

Vast majority of web developers today will use electron, as unfortunate as that is...

WinUI keeps being UWP, and by the way WPF is now officially in maintenance mode.

Your Silverlight replacement would be OpenSilver.

The cross platform toolkits would be MAUI (nee Xamarin) and Blazor.

Electron is the new Active Desktop/XUL, its fashion phase will eventually fade away.

> WPF is now officially in maintenance mode.

Can you share the official source of this statement?

And the web nostalgists will target Ruffle.
