I wouldn't call this a regression, just unsupported platform for now.

We do have a WinUI PR open, which might solve your issue. We also have another PR with .NET 6 support, which I need to finish up.

So won't do anything about this binding error you get until those get in. You could instead just use regular XAML bindings or whatever WPF/WinUI provides.

This is also the issue that I have run into. Is there a timeframe to merge this into the main trunk or is there a way forward for the interim?
