Solution

This suggests an activation problem on WCF. Metadata are not exposed when there is a problem in your service/config/env.

To get the error message try to open http://localhost:12659 in your browser and/or check event logs.

As it's a nettcpbinding, the config is a little more complex especially if your are hosting the service under IIS : check that WAS Service is started, Net Tcp Listener Service is Started, net.tcp is in Activated protocols for your web site, configured bindings conftoins ntc.tcp on port 1127 , ...). You may also try a basicHttpBinding first.

For debugging purposes set the includeExceptionDetailInFaults attribute to true

  <behaviors>
        <serviceBehaviors>
            <behavior name="CalculatorServiceBehavior">
                <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
                <serviceDebug includeExceptionDetailInFaults="true"/>
            </behavior>
        </serviceBehaviors>
    </behaviors>
