Edit

Manages the session between an application and the system compositor process.

The Compositor class creates an instance of the Compositor for the application that can be used as a factory for a variety of types in the Windows.UI.Composition namespace spanning the visual layer, effects system and animation system. The Compositor class also manages the lifetime of objects created from the factory.

Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Remarks

The Compositor implicitly synchronizes changes made to associated visuals to ensure they get applied in a transactional manner.

See the Composition UI Overview and Composition Visual Tree Overview for more information.

New instances of Compositor must be created on a thread that has a CoreDispatcher.
