By default, when you do an Add Service Reference operation, the WCF runtime will generate the client-side proxy for you.
The simplest way to use it is to instantiate the client proxy with a constructor that takes no parameters, and just grab the info from the
This requires the config file to have a <client> entry with your service contract - if not, you'll get the error you have.
YourServiceClient proxy = new YourServiceClient();
But the client side proxy class generated by the WCF runtime also has additional constructors - one takes an endpoint address and a binding, for instance:
BasicHttpBinding binding = new BasicHttpBinding(); binding.Security.Mode = BasicHttpSecurityMode.Transport; EndpointAddress epa = new EndpointAddress("http://example.com/api/?wsdl"); YourServiceClient proxy = new YourServiceClient(binding, epa);
With this setup, no config file at all is needed - you're defining everything in code. Of course, you can also set just about any other properties of your binding and/or endpoint here in code.
