How can I change the endpoint address programmatically in the client site?
proxy.Endpoint.Address = new EndpointAddress("http://newaddress");
where proxy
is an instance of the client class generated when importing the WSDL. Or you can specify the address when creating the client proxy:
var endpoint = new EndpointAddress("http://newaddress");
var proxy = new SomeClientProxy("BasicHttpBinding_IHelloWorld", endpoint);
