Called to cancel an ongoing domain operation.
Assembly: System.Windows (in System.Windows.dll)
Method used to cancel an ongoing domain operation. If the domain operation is a domain join and is occurring via a LicenseAcquirer, calling this method will also cancel license acquisition (and, indirectly, playback will fail with a license acquisition failure error message if license acquisition was occurring via a MediaElement). For domain leave, this method only cancels the asynchronous operation informing the server that the client has left the domain. Refer to LeaveDomainAsync for more information.
