How do you go about creating an overlay window? Where do you put it so it expands on top of the rest of the window? There seems to be no documentation on how do use this library whatsoever.

Also, MessageDialog doesn't work. It throws a ResourceReferenceKeyNotFoundException when MessageDialog.ShowAsync() is called. The additional information says " 'Framework.UI.Controls.OverlayWindow' resource not found." Do I need to setup a resource here? If so, how do I do that?

I've tried looking at the example (Framework.UI.TestHarness) code to figure out both situations but it doesn't even compile.
