PresentationSource Class
Provides an abstract base for classes that present content from another technology as part of an interoperation scenario. In addition, this class provides static methods for working with these sources, as well as the basic visual-layer presentation architecture.
Assembly: PresentationCore (in PresentationCore.dll)

![]() | CompositionTarget | Gets the visual target for the visuals being presented in the source. |
![]() ![]() | CurrentSources | Returns a list of sources. |
![]() | Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
![]() | IsDisposed | When overridden in a derived class, gets a value that declares whether the object is disposed. |

![]() ![]() | FromDependencyObject(DependencyObject) | Returns the source in which a provided DependencyObject is presented. |
![]() ![]() | FromVisual(Visual) | Returns the source in which a provided Visual is presented. |
![]() | GetCompositionTargetCore() | When overridden in a derived class, returns a visual target for the given source. |

![]() | RemoveSource() | Removes a PresentationSource derived class instance from the list of known presentation sources. |
![]() ![]() | RemoveSourceChangedHandler(IInputElement, SourceChangedEventHandler) | Removes a handler for the SourceChanged event from the provided element. |
![]() | RootChanged(Visual, Visual) | Provides notification that the root Visual has changed. |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
