Question:You create a Microsoft ASP.NET application by using the Microsoft .NET Framework version 3.5. The application
consumes a Microsoft Windows Communication Foundation (WCF) service.
The WCF service exposes the following method:
[WebInvoke]
string UpdateCustomerDetails(string custID);
The application hosts the WCF service by using the following code segment:
WebServiceHost host = new WebServiceHost(typeof(CService), new Uri("http://win/"));
ServiceEndpoint ep = host.AddServiceEndpoint(typeof(ICService),
new WebHttpBinding(), "");
You need to invoke the UpdateCustomerDetails method.
Which code segment should you use?
A WebChannelFactory wcf = new WebChannelFactory(new Uri("http://
win"));
ICService channel = wcf.CreateChannel();
string s = channel.UpdateCustomerDetails("CustID12");B WebChannelFactory wcf = new WebChannelFactory(new Uri("http://
win/UpdateCustomerDetails"));
ICService channel = wcf.CreateChannel();
string s = channel.UpdateCustomerDetails("CustID12");C ChannelFactory cf = new ChannelFactory(new WebHttpBinding(),
"http://win/UpdateCustomerDetails") ;
ICService channel = cf.CreateChannel();
string s = channel.UpdateCustomerDetails("CustID12");D ChannelFactory cf = new ChannelFactory(new BasicHttpBinding(),
"http://win");
cf.Endpoint.Behaviors.Add(new WebHttpBehavior());
ICService channel = cf.CreateChannel();
string s = channel.UpdateCustomerDetails("CustID12");
