Any Source Multicast Client. Begin Join Group(AsyncCallback, Object) Method
This API is now obsolete.
Binds the socket and begins a join operation to the multicast group to allow datagrams to be received from any group participant.

[System.Obsolete("This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.", true)] public IAsyncResult BeginJoinGroup (AsyncCallback callback, object state);
member this.BeginJoinGroup : AsyncCallback * obj -> IAsyncResult
Public Function BeginJoinGroup (callback As AsyncCallback, state As Object) As IAsyncResult
A callback method to invoke when the operation completes.
Optional state information to pass to the
callback method for this operation.
The multicast group has already been joined or a join operation is currently in progress.
An error occurred when attempting to access the socket.
The BeginJoinGroup method binds a UDP multicast socket to a local port and joins a multicast group to allow datagrams to be received from any multicast group participant. The local port and multicast group address are specified in the UdpAnySourceMulticastClient constructor.
The method specified in the
callback parameter is invoked when the operation to join the multicast group has completed.
If required by the runtime, the BeginJoinGroup 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.
