Not more so than Windows.

No. .NET Core and Wine does not solve the same problem.

.NET Core only allows you to run applications written for .NET, which isn't most applications.

And in comparison, Wine does not try to be a .NET Common Language Runtime (CLR).

dotnet core does not now and probably will never support WinForms or WPF (edit: in a cross platform way that tools like WINE can offer)

It’s a very nice tool, but the two dominant and old GUI frameworks for windows require win32 api for a bunch of stuff the last time i looked and there’s no getting away from it.

"The Real" WPF maybe not, but when it comes to XAML based, then there's: https://avaloniaui.net/

it is "A cross platform XAML Framework for .NET Framework, .NET Core and Mono."

So that is in a realm of possibility.

The "supports" thing is the other way around: Of course .net core would support them on other platforms, but Winforms and WPF don't support other platforms than Windows (Winforms because it's tightly coupled to Win32 [AFAIK] and WPF because it's mostly built on DirectX [AFAIK]).

That said: (AFAIK) Both run on Wine in some versions.

.NET 6 will include a cross platform UI library based on Mono's implementation of WinForms IIRC.

MAUI is basically Microsoft consolidating Xamarin fully into .NET and might consolidate things from their own UI frameworks as well.

.NET Core does support both WinForms and WPF, but only on Windows (with no plans for other OS). Maybe that's what you meant and I just misunderstood? Regardlessly it used to be the case that .NET Core didn't support those GUI frameworks even on Windows, so it's a bit confusing.

yes that’s right. i’ll edit.
