Windows Forms is good, but limited. WPF is almost perfect, but Avalonia is like that + cross platform.
The other ms gui frameworks are a waste of time, skip those.
But since they pivoted to cloud, web AI and they don't profit too much from people building desktop and mobile apps, I guess Microsoft won't invest much resources into MAUI or any GUI toolkit.
