protected virtual IAsyncResult OnBeginOfflineAnnouncement (System.ServiceModel.Discovery.DiscoveryMessageSequence messageSequence, System.ServiceModel.Discovery.EndpointDiscoveryMetadata endpointDiscoveryMetadata, AsyncCallback callback, object state);
abstract member OnBeginOfflineAnnouncement : System.ServiceModel.Discovery.DiscoveryMessageSequence * System.ServiceModel.Discovery.EndpointDiscoveryMetadata * AsyncCallback * obj -> IAsyncResult
override this.OnBeginOfflineAnnouncement : System.ServiceModel.Discovery.DiscoveryMessageSequence * System.ServiceModel.Discovery.EndpointDiscoveryMetadata * AsyncCallback * obj -> IAsyncResult
Protected Overridable Function OnBeginOfflineAnnouncement (messageSequence As DiscoveryMessageSequence, endpointDiscoveryMetadata As EndpointDiscoveryMetadata, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters
