Soap endpoint identity

Jeg har overtaget en SOAP kode, som jeg ikke rigtigt kan debugge.

Jeg får kontinuerligt en fejl besked når jeg forsøger at invoke metoden i Servicen.

The Address property on ChannelFactory.Endpoint was null.  The ChannelFactory's Endpoint must have a valid Address specified.
  at System.ServiceModel.ChannelFactory.CreateEndpointAddress(ServiceEndpoint endpoint)
  at System.ServiceModel.ChannelFactory`1.CreateChannel()
  at System.ServiceModel.ClientBase`1.CreateChannel()
  at System.ServiceModel.ClientBase`1.CreateChannelInternal()
  at System.ServiceModel.ClientBase`1.get_Channel()
  at LoggingServiceClient.Add(String name, String level, String time, String message





Jeg har dette stående i min app.config


<endpoint address ="" binding="webHttpBinding" contract="Library.Logging.ILoggingService">
          <!--

              automatically.
          -->
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <!-- Metadata Endpoints -->
