Navigating Win32 App Development with WinUI and WPF
summary
Compares concrete migrations and demos: use WinUI 3 to reuse UWP work, get ItemsView/AnnotatedScrollbar backed by ScrollView and Composition InteractionTracker, and run AOT .NET 8 for ~45% smaller distribution and ~50% faster launches; Photos reports 2.5× faster cold start and image loads. Use WPF to apply .NET 9 theming (Preview 4) and keep large C# codebases. Shows packaging steps, calling WinApp SDK APIs from WPF (compact overlay) and raw Win32 C++ (Lottie, 3D scene graph), and running downlevel to 1.5 billion Windows devices.
