I used to heavily advocate for .NET Native and C++/CX with WinRT, as for me that is what .NET 1.0 should have been all along.
Nowadays I just can't, just keep using Win32 and Forms/WPF until the civil war comes to an end.
I was worried. Not that I like the ridiculous Windows 10 Settings app, but I do like UWP+Xamarin.
I recently discovered that the Visual Studio installer is using Electron.
For all the criticism of Apple regarding backwards compatibility they have a clear story on the UI for macOS. Cocoa -> SwiftUI.
The backslash was big enough that they rewrote it back into WPF.
There is a tweet from the team about it, and you can validate yourself by running the latest installer versions.
Regarding Apple, no they don't, you are missing Catalyst, and the mess about what which OS features does each of them support.
There is one ATP podcast episode where they go on a side rant regarding their state.
