You can remove app. Config and use code to configure it directly

protected Override voidOnStart (string[] args) {    if(ServiceHost! =NULL) {servicehost.close (); }    Try{serviceHost=NewServiceHost (typeof(Windowsservice1.calculatorservice),NewUri ("Http://127.0.0.1:9999/CalculatorService") ); ServiceMetadataBehavior SMB= servicehost.description.behaviors.find<servicemetadatabehavior>(); if(SMB = =NULL) {SMB=NewServiceMetadataBehavior (); } SMB. Httpgetenabled=true; Smb. Metadataexporter.policyversion=policyversion.policy15;        SERVICEHOST.DESCRIPTION.BEHAVIORS.ADD (SMB); Servicehost.addserviceendpoint (Servicemetadatabehavior.mexcontractname, METADATAEXCHANGEBINDINGS.CREATEMEXHTTPB Inding (),"Mex"); Servicehost.addserviceendpoint (typeof(ICalculator),NewWshttpbinding (),"");    Servicehost.open (); }    Catch(Exception ex) {}}

1. Test Tool using WcfTestClient

2. Client testing:

usingSystem;usingSystem.ServiceModel;usingWindowsService1;namespacetestwindowsserviceclient{classProgram {Static voidMain (string[] args) {            /*//http ICalculator client = Channelfactory<icalculator>. CreateChannel (New Wshttpbinding (), New EndpointAddress ("http://127.0.0.1: 9999/calculatorservice ")); */            //TCPICalculator client = channelfactory<icalculator>. CreateChannel (Newnettcpbinding (),NewEndpointAddress ("Net.tcp://127.0.0.1:9999/calculatorservice")); DoubleRET = client. ADD (23.0,2.0); Console.WriteLine ("Add Result: {0}", ret);        Console.read (); }    }}
