I was trying to start coding in C# using Visual Studio on my Mac, following a tutorial on how to create a Windows form application, here (Visual studio for Mac 2022 preview) I can't see any of this, so, how can I do that? Thank you for the help!
No, WinForms is not supported on MacOS. There are other GUI alternatives (Avalonia, or the new Maui) that are.
It might be possible to get a WinForms app to work with Mono, but I wouldn't try that for a new project, because Mono is deprecated and only works with .NET Framework, which in turn is not supported as a development environment on the Mac.
