WCF Error A SOAP 1.2 message is not valid when sent to a SOAP 1.1 only using wsHttpBinding

Question

I am trying to consume a service which I have no control over and have been given just the WSDL to consume. The service requires a certificate for authentication. My configuration for the certificate is fine and I get an error when I try and call the service as below:

The content type text/xml;charset=UTF-8 of the response message does not match the content type of the binding (application/soap+xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 274 bytes of the response were: 'soap:VersionMismatchA SOAP 1.2 message is not valid when sent to a SOAP 1.1 only endpoint.'.

I have tried different this like using a customBinding but I landed up with a total new number of more errors and feel am not getting anyway. Can you please assist?

I have managed to figure it out with tweaks and trials. In order to solve is I change to basicHttpsBinding which took me another day or two to figure out the default transport clientCredentialType is None and you need to configure a custom binding as below. I wish WCF would tell you why or give a solution to error you get, because it was such a pain. From one error description to the next nonstop.

<bindings>
      <basicHttpsBinding>
        <binding name="SecureHubBinding">
          <security>
            <transport clientCredentialType="Certificate"  />
            <message clientCredentialType="Certificate" />
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
