Gets the domain of the LocalMessageReceiver that this sender will send messages to.
Assembly: System.Windows (in System.Windows.dll)
If this property is null, then the sender can send messages only to a receiver on the same domain. Otherwise, if the receiver's NameScope property is set to Domain, then this property must be set to the name of the receiver's domain. Additionally, if the receiver's NameScope property is set to ReceiverNameScope.Global, then this property must be set to LocalMessageSender.Global.
