The EndJoinGroup method completes an asynchronous bind to a socket and join operation to a multicast group.

If required by the runtime, the EndJoinGroup 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 AccessDenied.

If there is a socket failure while performing the join group operation, a SocketException is thrown. The error received is specified as a member of the SocketError enumeration.
