For those losing count, Windows 8 introduced WinRT with three UI models (phone/tablet/desktop), Windows 8.1 introduced UAP and reduced the UI models to 2 (phone/tablet and desktop), Windows 10 introduced UWP and merged all UI models into a universal one (U in UWP).
.NET Native and C++/CX were introduced as a reboot of the Windows platform where COM takes again the center stage, as if .NET as such never happened and we got the evolution of VB 6 instead.
Due to lack of update, and multiple rewrites, they came up with WinUI 3.0 and WinAppSDK, which dropped .NET Native and C++/CX, .NET and C++/WinRT are still lacking versus the former in Visual Studio tooling for WinUI development, WinUI 3.0 is still years behind UWP features, many key people that used to be in the community calls have either left Microsoft, or moved into Azure.
Now they are rebooting it yet again? Good luck convincing those of us that had enough from this mismanagement.
