This is what I'm wondering. How dysfunctional is microsoft that they shipped a react-based start menu? It reads like satire, "Windows 11 is so bad that even microsoft doesn't use native controls".
React Native is a way of orchestrating a UI comprised of native controls.
In retrospect, calling it React probably caused more problems than it brought benefits, and makes little sense - like Java vs JavaScript.
The team that killed C++/CX, said it isn't their problem that there aren't Visual Studio integrations like C++/CX, and eventually left C++/WinRT in maintenance and nowadays is responsible for windows-rs repo. Better not expect too much from that repo as well.
Welcome to Microsoft politics.
