The port of VS to WPF was definitely not a showcase for WPF capabilities. Pretty much everything was worse or slower after the port. And a ton of features was missing. Even now the customization of toolbars is not as elegant as it was on 2008. Not a surprise that they didn’t use XAML for any other big application

UWP/WinUI/Metro uses XAML and Microsoft was very committed to that for a while. UWP didn't really pan out, but that was for reasons other than XAML and WinUI IMO.
