Does WCF support WS-Security with SOAP 1.1?

Question

I need to call some 3rd Web services that require WS-Security. I created a WCF endpoint with the following configuration:

<system.serviceModel>
  <bindings>
    <wsHttpBinding>
      <binding name="TestBinding">
        <security mode="TransportWithMessageCredential">
          <message clientCredentialType="Certificate" />
        </security>
      </binding>
    </wsHttpBinding>
  </bindings>
  <behaviors>
    <endpointBehaviors>
      <behavior name="TestBehavior">
        <callbackDebug includeExceptionDetailInFaults="true" />
        <clientCredentials>
          <clientCertificate findValue="Acme" storeLocation="CurrentUser" storeName="My" x509FindType="FindBySubjectName" />
          <serviceCertificate>
            <authentication certificateValidationMode="PeerOrChainTrust" />
          </serviceCertificate>
        </clientCredentials>
      </behavior>
    </endpointBehaviors>
  </behaviors>
  <client>
    <endpoint address="https://acme.com/webservices" binding="wsHttpBinding" bindingConfiguration="TestBinding" behaviorConfiguration="TestBehavior" contract="AcmeContract" name="AcmeEndpoint"></endpoint>
  </client>
</system.serviceModel>

The problem is that the 3rd party servers a throwing the following exception:

Received protocol '_http://schemas.xmlsoap.org/wsdl/soap12/', required protocol '_http://schemas.xmlsoap.org/wsdl/soap/'.

I understand that using the wsHttpBinding will cause WCF to send a SOAP 1.2 request while using the basicHttpBinding will result in a SOAP 1.1 request. Since the WS-Security parts are required, as I understand it, I have to use the wsHttpBinding. My question is how do I force a SOAP 1.1 request? What are my options?

Answer 1

In order to use WS-Addressing (wsHttpBinding), but with SOAP 1.1 (SOAP 1.2 being the default), you need to define a custom WCF binding (e.g. in config) and use that:

<bindings>
   <customBinding>
      <binding name="WsHttpSoap11" >
         <textMessageEncoding messageVersion="Soap11WSAddressing10" />
         <httpTransport/>
      </binding>
   </customBinding>
</bindings>

and then in your endpoint definition, use:

<endpoint name="WsSoap11"
    address="....."
    binding="customBinding"
    bindingConfiguration="wsHttpSoap11"
    contract="....." />

Of course, you can extend the custom binding defined above with additional properties, e.g. <reliableMessaging> or others.
