        {
            // Set up asyncResult for overlapped WSARecvFrom.
            // This call will use completion ports on WinNT and Overlapped IO on Win9x.
            asyncResult.SetUnmanagedStructures(buffer, offset, count, socketAddress, true);

            int bytesTransferred;
            SocketError errorCode = Interop.Winsock.WSARecvFrom(
                handle,
                ref asyncResult._singleBuffer,
                1,
                out bytesTransferred,
