WebView2 would probably be the way to go, now... at least for Windows as the target.

Even the "port to WinUI" from UWP for the PhotosApp, is in similar vein, making use of Webview2 instead of native Windows.

When Microsoft teams behave as such, why should we keep paying attention?

For native Windows, Forms, WPF, and even MFC is way better in VS tooling than WinUI C++.

I can't tell if this is sarcasm. I really hope it is
