WinForms and its Visual Studio designer are still broken, WPF is still riddled with bugs and was declared obsolete in ~2017 in favor of UWP, UWP is marked obsolete in favor of WinUI, and WinUI's OSS release was postponed just two days ago because it's not ready.
Microsoft is marketing .NET 6 as the replacement for .NET Framework but you still cannot properly do desktop UI with it. I honestly don't understand why they are pushing more and more features when they cannot complete the ones they started years ago. Not to mention that porting WinForms from .NET Framework to .NET 6 requires a rewrite for anything more complex than a Hello World.
