Completes the asynchronous join group operation to a multicast group.
Assembly: System.Net (in System.Net.dll)
The method completes an asynchronous bind to a socket and join operation to a multicast group.
If required by the runtime, the method also performs a policy check to verify that the client is allowed to access the multicast group. If the client is not allowed access, a SocketException is thrown with SocketError.AccessDenied.
