NetTcpBinding binding = TcpBindingUtility.CreateNetTcpBinding();
EndpointAddress endpoint = new EndpointAddress(@"net.tcp://localhost:8049/IService/");
Agent<IService> client = new Agent<IService>(CallBackInstance, binding, endpoint);
serviceInstance = client.ChannelFactory.CreateChannel();
serviceInstance.Register("TestSystem"); //service Call

Hi Nrk_hi,

You could check service channel state like this.

if (proxy.State == CommunicationState.Faulted)
{
  //...
  //"You have lost your connection to the service. Please make your request(s) again."
  CreateProxy();
  proxy.StartOver();
  return;
}
