Error message when trying to add a Service Reference

I'm trying to add a service reference to my silverlight project from a file stored on my hosting server. When I put the link in I get the following error:

The document at the url http://www.lloydp.co.uk/Test/WcfRectangleService.dll was not recognized as a known document type.

Can anyone tell me what the problem is? The XML file hasn't been altered in anyway, I'm new to all this so I'm a bit lost at the minute.

Thanks in advance,

You are pointing at the URL http://www.lloydp.co.uk/Test/WcfRectangleService.dll -- note the .dll extension. This is the internal code for the service. So the web server is returning a bunch of binary code rather than a XML document.

Point at the .svc file instead -- this is the service endpoint.
