This method is public so that any thread can probe to see if it has access to the DispatcherObject.VerifyAccess()
Verifies that the calling thread has access to this object.
public void VerifyAccess()Remarks
Only the dispatcher thread may access DispatcherObjects.
This method is public so that derived classes can probe to see if the calling thread has access to itself.This is only verified in debug builds.
