i tried to start multiple ServicePublishers on one machine and on the second ServicePublisher you get an exception : Only one usage of each socket address (protocol/network address/port) is normally permitted this happens in line 72 while calling : this.listener = new UdpClient(UdpMulticastGroupSettings.ServerPort); any solution on this available?

  SOLUTION:
  
  in the ServiceProvider use AdvUdpClient instead of UdpClient
  
  impl for AdvUdpClient:
  
public class AdvUdpClient : System.Net.Sockets.UdpClient
{
public AdvUdpClient( int port )
{
this.Client.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.ReuseAddress,1);
this.Client.Bind( new IPEndPoint(IPAddress.Any, port) );
}
}
