Represents the base class for all XamlDirect APIs. All of the XamlDirect APIs are instance methods of this class.
XamlDirect is an API for accessing Xaml at a more primitive level for better CPU and working set performance.
This documentation applies to WinUI 2 for UWP (for WinUI in the Windows App SDK, see the Windows App SDK namespaces).

Tip
The WinUI 3 Gallery and WinUI 2 Gallery apps include interactive examples of most WinUI 3 and WinUI 2 controls, features, and functionality.
If installed already, open them by clicking the following links: WinUI 3 Gallery or WinUI 2 Gallery.
If they are not installed, you can download the WinUI 3 Gallery and the WinUI 2 Gallery from the Microsoft Store.
You can also get the source code for both from GitHub (use the main branch for WinUI 3 and the winui2 branch for WinUI 2).
