Cancels a license acquisition.
Assembly: System.Windows (in System.Windows.dll)
This method is called to cancel a license acquisition. If the license acquisition is occurring via a MediaElement, calling this method causes playback to fail with a "license acquisition failure" error. If domain acquisition is occurring via an automatic domain join, this method also cancels that domain acquisition.
