WPF was really nice from what I remember of it. MVVM was super easily integrated with XAML.

MVVM is great if you want to unit test all your UI code but who wants to do that.

For me the whole thing was cumbersome and nowhere near as productive as WinForms. Not only that but problems it purported to solve like high-dpi support still had issues.

With some more work like better Visual Studio integration and maybe some compiler magic it could have been fantastic.
