Assembly: WindowsBase (in windowsbase.dll)
Only the thread that the Dispatcher was created on may access the DispatcherObject directly. To access a DispatcherObject from a thread other than the thread the DispatcherObject was created on, call Invoke or BeginInvoke on the Dispatcher the DispatcherObject is associated with.
Subclasses of DispatcherObject that need to enforce thread safety can do so by calling VerifyAccess on all public methods. This guarantees the calling thread is the thread that the DispatcherObject was created on.
A DispatcherObject cannot be independently instantiated; that is, all constructors are protected.
Objects that derive from DispatcherObject have thread affinity.
Any public static members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
This object can be accessed only from the thread on which it was created. Attempts to access it from other threads will throw an InvalidOperationException. Invoke or BeginInvoke provide support for marshalling work to the correct thread.
