XamlCompiler error WMC0020: Cannot add 'DataGrid' into the collection property 'Children', type must be 'UIElement'

Create a new project using the WinUI 3.0 Alpha C# "Blank App (WinUI UWP)" template.
Add [Microsoft.Toolkit.Uwp.UI.Controls] DataGrid to Page.

@infoequipt The data grid in the toolkit is built on top of the platform xaml (Windows.Ui.Xaml). WinUI3 is the same XAML codebase that has been decoupled from the OS (and has an updated namespace Microsoft.UI.Xaml). The reason I believe you are seeing is that the datagrid is not compiled against WinUI3. We need a version of the toolkit that targets WinUI3 for that to work. @nmetulev and @MikeHillberg This might make sense to track in the toolkit repo.

Thanks Ranjesh, I thought that might be the case.

Hopefully, there will be work started on a new DataGrid before the stable release of WinUI 3 Desktop.

This should be extended to all of the toolkit, not just data grid.

I filed a bug in Windows Community toolkit to track this.
CommunityToolkit/WindowsCommunityToolkit#3106

@Austin-Lamb @MikeHillberg @michael-hawker as FYI.
