WCF endpoints are driving me insane

Here's what I do:

PortClient client = new PortClient(); // from the service reference

EndpointAddress endpointAddress;

if (local)
    endpointAddress = new EndpointAddress("http://local/Service.svc");
else
    endpointAddress = new EndpointAddress("http://remote/Service.svc");

client.ChannelFactory.CreateChannel(endpointAddress);
client.RemoteMethod();

etc.
