Describe the bug
This is a minimal WinUI 3 desktop app written in C++, hosting a WinUI 3 runtime component written in C# to display the Community Toolkit DataGrid.
When attempting to declare the DataGrid in a XAML file, InitializeComponent fails with the WinRT error
0x802B000A: 'Cannot create instance of typeMicrosoft.UI.Xaml.Controls.XamlControlsResources'.When loading the DataGrid in the code-behind, a
System.TypeInitializationExceptionoccurs, with the internal exception being aNullReferenceException: 'Object reference not set to an instance of an object'.Steps to reproduce the bug
However, our host application is written in winrt/c++, which means we have to load the components as external winui3-runtime components.
Expected behavior
WinRT Error and TypeInitializationException should not occur.
