Can't update WCF Service Reference - Service Works

Question

I can't update my WCF-Service Reference after adding a new method. If i undo my changes it won't work, too. If i call the URI: http://192.168.1.175:8001/WS i can see the XML-File from the Service with all the methods. My client Application can also communicate with the server. If i enter the URI in the "WcfTestClient.exe" i'll get the same error as when i'll update my Service Reference:

HTTP-Status 503: Service Unavailable.

help appreciated.... :)

I ran into this issue today. After poking around on the web I came to the conclusion there was something being cached somewhere. I search my computer for all instances of the service's DLL (Found 19, BTW) and deleted all of them. After rebuilding, everything started working as it should.
