Description of the new feature/enhancement

I'm creating a WinUI 3 Desktop application (using VS 2022 17.3 Blank App WinUI 3 in Desktop template) where I'd like to use the Windows Terminal API to create a terminal window control to use inside my application.

I started by looking at your GUIConsole.WPF sample that is written in WPF for .NET Framework 4.6.1.

I tried to port the classes and the XAML window but I'm not able to let it work. I still have errors both on XAML and on code.

Proposed technical implementation details

Can you please add a new version of the code sample that is written using the new Windows App SDK v1.1?
