WindowsAppSDK

.. and how many of the Microsoft applications actually use WinUI3? As far as I can tell they're doing their own thing (Office) or are Electron (Teams) or, at least in Windows 10, haven't actually been updated from WinForms. The overhead of WinUI3 is pretty huge. The visual designer, a winning feature of Visual Studio for decades, is AWOL. Why? It's XAML, the same as the previous XAML designer! It's just .. broken? The backward compatibility story is a disaster: you can get stuck in the UWP sandbox https://github.com/microsoft/WindowsAppSDK/issues/1780 What's the big Microsoft WinUI3 flagship app, then? Something people are actually using? Rather than just a few system dialogues. (How many Win11 settings pop up a Win32 dialogue box, still?)

Ignore all the talk about WinUI 3.0 being the future, and check the issues on the following repos: https://github.com/microsoft/microsoft-ui-xaml https://github.com/microsoft/WindowsAppSDK https://github.com/microsoft/cppwinrt https://github.com/microsoft/CsWinRT
