Nah, it is so bad, that on BUILD 2024, they have brought back first level status to WPF.

No one burned with WinRT history since Windows 8, is ever touching WinUI, unless they are Microsoft employees on WinDev, or companies with sunken costs trying to keep their products around.

Except it's still missing a lot of controls, further development and bug fixes are practically at a standstill, and despite what TFA says, there is no visual designer support (which is a dealbreaker for many multidisciplinary teams).

As someone currently involved in switching our app from MFC, I really want to like MFC, but Microsoft's absolutely addled management of the whole thing is making it really difficult.
