Win32 Xaml App Samples

C++ samples that demonstrate basic Win32 use of Xaml using DesktopWindowXamlSource, also known as Xaml Islands.

• Minimal - The app client area is all Xaml. The markup is stored as a string and parsed at runtime. Less that 150 lines of code with 50 of it being markup (the NavigationView stolen from Terminals Settings UI)

• Multi Window App - A multi-window Win32 app that uses Xaml. This hooks up some handlers to the markups contents to demonstrate responding to Xaml originated events.

• Multi Xaml Mulit Window App - Multi window app that creates 2 islands in each window. Mostly a diagnostic case for testing.

Limitations

• Not using WinUI 2.x, using System Xaml instead.
• Does not implement accelerator handling or any integration with Win32 UI (who wants to use Win32 UI anyway!).
• No Xaml Application object, so no way to provide custom metadata.
• Intellisense in the .xaml files is broken, VS is confused seeing a .xaml file in a Win32 app project type.

Debugging tips

Look in the debugger output window for Xaml parsing errors, it identifies line and offset of the error.
