Question

I have WCF service. Here is configuration

  <basicHttpBinding>
    <binding name="EmergencyRegistratorBinding">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Windows" />
      </security>
    </binding>
  </basicHttpBinding>

And service configuration

  <service behaviorConfiguration="Default" name="Breeze.AppServer.Emergencies.EmergencyRegistrator">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="EmergencyRegistratorBinding"
        contract="Services.IEmergencyRegistrator" />
  </service>

Everything worked fine. But I needed to change basicHttpBingind to DuplexBinding.
I have added extention:

<extensions>
  <bindingElementExtensions>
    <add name="pollingDuplex" type="System.ServiceModel.Configuration.PollingDuplexElement, System.ServiceModel.PollingDuplex"/>
  </bindingElementExtensions>
</extensions>

And changed mentioned above lines to:

  <customBinding>
    <binding name="DuplexmergencyRegistratorBinding">
      <binaryMessageEncoding/>
      <pollingDuplex maxPendingSessions="2147483647" maxPendingMessagesPerSession="2147483647" inactivityTimeout="02:00:00" serverPollTimeout="00:05:00"/>
      <httpTransport authenticationScheme="Negotiate"/>
    </binding>
  </customBinding>

and

  <service behaviorConfiguration="Default" name="Breeze.AppServer.Emergencies.EmergencyRegistrator">
    <endpoint address="" binding="customBinding" bindingConfiguration="DuplexmergencyRegistratorBinding" contract="Breeze.Core.Services.IEmergencyRegistrator" />
    <endpoint address="mex" binding="customBinding" bindingConfiguration="DuplexmergencyRegistratorBinding" contract="IMetadataExchange"/>
  </service>

I have added Service Reference to WCF project. Reference was successfully added but Reference.cs was almost empty.

When I uncheck option “Reuse types in referenced assemblies”
Code is generated but there above 10 thousands lines instead of ~500

I run svcutil and I’ve got next:

svcutil.exe http://localhost/Breeze.Workstation/Emergencies/EmergencyRegistrator.svc?wsdl

Attempting to download metadata from ‘http://localhost/Breeze.Workstation/Emergencies/EmergencyRegistrator.svc?wsdl’ using WS-Metadata Exchange or DISCO.

I’m quite new to WCF services. I hope somebody will be able to help me.
Thanks.

Answer 1

I’ve solved that.
Empty reference was due to some problems with ambiguous types. When I fixed it, reference.cs file generated well.

So, solution is to look not only at errors, but at warnings too. I have found there all information what I need for my problem. Happy codding
