From link:[^]You may also notice that VS2008 also issues another error
There was an error downloading metadata from the address. Please verify that you have entered a valid address.
Well this means that service is not accessible and VS2008 cannot download metadata required for building the service. In our case, we know the reason – someone missed the Troubleshooting Tip#1. But in general case a number of reasons may cause this error all of which boils down to one thing – VS2008 cannot connect to the service and cannot download data required for building reference.
Anyway, if you see the error, click OK in Error dialog, close WCF Service Host window, click Cancel in Add Service Reference, save all files, close and re-open VS2008 as administrator, open WCFinVS2008 solution and repeat steps 2 from above.
