Represents the composited display surface for an app. This class is mainly for Microsoft DirectX content interop scenarios.
The CompositionTarget class has these types of members:
The CompositionTarget class has these events.
|Rendering||Occurs when the core rendering process renders a frame.|
|SurfaceContentsLost||Occurs when an underlying major change occurs, such as a DirectX device change. Typically the application must regenerate its surface contents when notified of this event.|
The CompositionTarget class inherits methods from the Object class.
CompositionTarget has one member, Rendering. Rendering is a static event that is fired by the XAML rendering system overall, not by the Application, Window, Page or any other specific object part of an app. CompositionTarget's sole purpose is to provide this hook into the rendering process. That's mainly relevant only to DirectX content interop scenarios where you want to know when the XAML rendering happens, so that you can execute some DirectX code in response. For scenarios that don't involve DirectX content you probably won't need Rendering and can just rely on the XAML rendering system running and performing all your composition and layout.
