Asynchronous socket programming

[Rob]

Hello,

I've got a huge problem with async sockets.
I've created a networked virtual environment, using async socket programming.
The problem I face occurs when I close the listener socket. It listens using socket.BeginAcc ept(...).
When a client disconnects, the socket is disconnected like this:

try
{
socket.Shutdown (SocketShutDown .Receive);
}
catch
{
...
}

socket.Close();

(The application is still running now!)
Now, when an incoming call comes (which it just should ignore), my application crashes with:

Uncaugt exception in System.dll, InvalidOperatio nException in system.net.sock ets.Socket.Acce ptCallback..... .

How the hell can I catch this? Better, why does it still throw this? it is shutdown!

Thanks,
-- Rob.
