var client = new Sorgula(binding, new EndpointAddress("http://www.nameofthewebsitehere.com"));Just be aware that the class name might not match what you're currently using; I usually just type: var client = new S - then wait for the intellisense to pop up, then I'll go through the list of class names that sound like what I want and have the constructor parameters I want to pass. So don't be surprised if you have to do something like var client = new SorgulaClient(binding, new EndpointAddress("http://address.com"); or some other variant.
