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...
