WCF 4: Fileless Activation Fails On XP (IIS 5) that has SSL port enabled.

Question

I have a service being hosted in IIS on XP via fileless activation. The service starts fine when there is no SSL port enabled for IIS but when the SSL port is enabled, I get the error message:

System.ServiceModel.ServiceActivationException: The service '/SkillsPrototype.Web/services/Linkage.svc' cannot be activated due to an exception during compilation. The exception message is: A binding instance has already been associated to listen URI 'http://rcollet.hsb-corp.hsb.com/SkillsPrototype.Web/Services/Linkage.svc'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config. . ---> System.InvalidOperationException: A binding instance has already been associated to listen URI 'http://rcollet.hsb-corp.hsb.com/SkillsPrototype.Web/Services/Linkage.svc'. If two endpoints want to share the same ListenUri, they must also share the same binding object instance. The two conflicting endpoints were either specified in AddServiceEndpoint() calls, in a config file, or a combination of AddServiceEndpoint() and config.

My service model configuration is

  <system.serviceModel>
    <diagnostics wmiProviderEnabled="true">
      <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" maxMessagesToLog="3000"/>

    </serviceHostingEnvironment>
  </system.serviceModel>

When you look in the svclog file, there two base addresses that are returned when SSL is enabled, one for http and one for https. I suspect that this is part of the issue but I am not sure how to resolve it.

I can't post the full service log due to character limits on the post.

Answer 1

It figures after spending hours on this I resolve the issue shortly after posting.

It appears that the issue is related to using WebScriptServiceHostFactory. Instead I created a service entry with a kind attribute and now it works.

Here is the corrected configuration

  <system.serviceModel>
    <diagnostics wmiProviderEnabled="true">
      <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" maxMessagesToLog="3000"/>
    </diagnostics>
    <standardEndpoints>
      <webHttpEndpoint>
        <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true" />
      </webHttpEndpoint>      
    </standardEndpoints>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <!--Default settings for the webHttpBinding-->
        <binding>
           <security mode="None">
            <transport clientCredentialType="None"/>
          </security>
        </binding>
      </webHttpBinding>
    </bindings>
    <protocolMapping>
    </protocolMapping>
    <services>
      <service name="SkillsPrototype.ServiceModel.Linkage">
        <endpoint

      </service>
    </services>
