public interface IService1

{

[operationContract]

string GetData(int value);

} then at the client side followoing is the piece of code to obtin the proxyObject, to call the service .

string url = "htt://localhost:26800/service1.svc?wsdl";

EndPointAddress endPoint = new EndPointAddress (url);

BasicHttpBinding binding = new BasicHttpBinding();

----------------------------------------------------------------------------------

Console.WriteLine (ref, GetData(100)) ;

Options :

1. IService1 lref = new ChannelFactory (endPoint), CreateChannel();

2. IService1 lref = new ChannelFactory (binding, endPoint), CreateChannel();

3. IService1 lref = new ChannelFactory (binding), CreateChannel();
