Occurs when the Dispose method is called on this object.
public event EventHandler Disposed
The Disposed event is raised before any resources are released by the HwndSource. The Disposed event indicates that the object that raises the event is about to have all references to it removed.
Use Disposed and the IsDisposed property to avoid calling Dispose twice (which raises an exception).
