Very true. We just developed a brand new LOB desktop app and settled on sticking with WPF. WinUI has been dead for years imo.
On a side note, I still love WPF after working in it for 10 years. Maybe it's just familiarity, and it's a little verbose at times, but man it's a great framework when you know that you're doing.
We also settled on WPF for a new LOB Desktop application, this validates the decision. If you combine WPF with the CommunityToolkit MVVM, it’s a very nice framework to develop with.
