A Windows Communication Foundation (WCF) service implements a contract with one-way
and requestreply operations. The service is exposed over a TCP transport. Clients use a
router to communicate with the service. The router is implemented as follows. (Line
numbers are included for reference only.) 01 ServiceHost host = new
ServiceHost(typeof(RoutingService)); 02 host AddServiceEndpoint( 03
typeof(lSimplexDatagramRouter), 04 new NetTcpBinding0, “net.tcp:/flocalhostlRouter” 05);
06 List <ServiceEndpoints lep new List <ServiceEndpoint>0;t 07 lep.Add( 08 new
ServiceEndpoint( 09 ContractDescription.GetContract( 10 typeof(lSimplexDatagramRouter)
11), 12 new NetTcpBinding0, 13 new EndpointAddress|’nettcp://localhost: 8080/Logger”)
14) 15); 16 RoutingConfiguration rc new RoutingConfigurationO; 17 rC. FilterTable.Add(new
MatchAilMessageFilterO, lep); 18 host. Description. Behaviors. Add(new
RoutingBehavior(rc)); Request-reply operations are failing. You need to ensure that the
router can handle one-way and request-reply operations. What should you do?
