WPF_XamlIslands_v1 build error

[kmelmon]

Trying to build WPF_XamlIslands_v1 solution on a fresh clone produces this build error:

XamlCompiler error WMC1006: Cannot resolve Assembly or Windows Metadata file 'D:\Xaml-Islands-Samples\Samples\Managed\UILibrary\bin\Debug\UILibrary.winmd' 2>CSC : error CS0006: Metadata file 'D:\Xaml-Islands-Samples\Samples\Managed\UILibrary\bin\Debug\UILibrary.winmd' could not be found

Having the same issue. I have already converted a WinForms base that also can host WPF windows/elements from core3.1 to net5. Looking to replace the WinForms shell with WinUI3 but having issues getting that and WPF/WinForms to play nice. Came across this sample and unable to get it working with the same error: Error CS0006 Metadata file 'Xaml-Islands-Samples\Samples\Managed\UILibrary\bin\Debug\UILibrary.winmd' could not be found UWPApplication

Problem is still present.
