You're kidding, right? WSL is not related to cross-platform GUIs we're talking about, and .NET Core doesn't support Windows Forms/WPF - and probably never will, for the reasons mentioned above.

That's not completely true, while WSL doesn't help Windows GUI apps to be more cross-platform, it does help Linux GUI apps to work on Windows[0]

So to refer back to the top comment we could say that Microsoft is proposing WSL as a cross-platform API for GUI apps.

The real bonus are the TUI apps tho. No idea what Windows users did all the years without proper command line commands, now if they include a proper shell they could really make a dent in the Linux desktop stats

W11 only, sadly.

Hmm, you're right, I didn't see that part. It seems their original plans[0] have changed...

The parent's link? Maybe. But I guess this only means that W11 ships with an X server, right?

On Windows 10, you just need to install your own X server. I'm using VcXsrv with great success to use GUI software running on WSL1.

Ah, yes of course. I use it too :)

WSL lets people run their Linux apps with Linux GUIs on Windows. It makes Linux apps cross-platform, which makes sense if your business proposition is "literally all software runs on windows, and some software also runs on non-Windows. Choose wisely"

And, IIRC, .NET Core doesn't support WPF forms for legal/trademark reasons. But other MSFT supported .NET Forms libraries that happen to be API/feature compatible work on Windows/OSX/Linux/Android/iOS.

>.NET Core doesn't support Windows Forms/WPF

It does actually although you are correct in your general point.

Microsoft is also driving the development of React Native for Windows and MacOS.
