Is there a way to set the property of type 'Type' from xaml?

See original GitHub issue

I have a WinUI/UWP project. In my custom control I have a property of type Type. I tried to set it from xaml like ControlTemplate.TargetType property, but got an exception on InitializeComponent.

Windows.UI.Xaml.Markup.XamlParseException: 'The text associated with this error code could not be found.

Failed to assign to property ‘App11.MyControl.SomeProperty’. [Line: 17 Position: 26]’

Is there a way to set such properties from xaml?

Sample control

public class MyControl : Button
{        
        public Type SomeProperty { get; set; }
}

Xaml

<local:MyControl SomeProperty="Button" />

Thanks! You’re right, the Windows.UI.Xaml.Markup.XamlParseException text displayed by VS tricked me into thinking that you were using UWP XAML rather than WinUI 3.

As it turns out, this is a known issue that we’re already working on fixing, but we appreciate the report nonetheless!

This will be fixed in the WinUI 3 Preview 2 release.
