Error consuming Web service - content type text/xml;charset=utf-8 of the response message does not match the content type of the binding

Question

Hi all,
We are trying to interact with Documentum server through DFS exposed WCF which communicates through port 9443 and we are provided with documentum issued Public Key certificates. We have successfully imported the certificates in client machine and configured
the bindings as below in our .Net web application config file.
<system.serviceModel>
<bindings>
<wsHttpBinding>       
<binding
name="ObjectServicePortBinding1">
<security
mode="Transport">
<transport
clientCredentialType="None"
proxyCredentialType="None"
realm=""
/>
<message
clientCredentialType="Certificate"
algorithmSuite="Default"
/>
</security>
</binding>
<binding
name="QueryServicePortBinding">
<security
mode="Transport">
<transport
clientCredentialType="None"
proxyCredentialType="None"
realm=""
/>
<message
clientCredentialType="Certificate"
algorithmSuite="Default"
/>
</security>
</binding>
</wsHttpBinding>
</bindings>
Also, we set the message encoding as MTOM and the wcf client object initialization code snippet is as below,
ObjectServicePortClient
serviceClient = new
ObjectServicePortClient(new
WSHttpBinding("ObjectServicePortBinding1"),
new
EndpointAddress(UriUtil.ObjectServiceUri));
if (serviceClient.Endpoint.Binding
is
WSHttpBinding)
   WSHttpBinding
wsBinding = serviceClient.Endpoint.Binding as
WSHttpBinding;
wsBinding.MessageEncoding =
"MTOM".Equals(transferMode) ?
WSMessageEncoding.Mtom :
WSMessageEncoding.Text;
serviceClient.Endpoint.Behaviors.Add(new
ServiceContextBehavior(Config.RepositoryName,
Config.DocumentumUserName,
Config.DocumentumPassword));
When we execute the above code, we are getting error message as below,
Exception: The content type text/xml;charset=utf-8 of the response message does not match the content type of the binding (multipart/related; type="application/xop+xml"). If using a custom encoder, be sure that the IsContentTypeSupported
method is implemented properly. The first 407 bytes of the response were: '<?xml version="1.0" ?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><S:Fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope"><faultcode>S:VersionMismatch</faultcode><faultstring>Couldn't
create SOAP message. Expecting Envelope in namespace http://schemas.xmlsoap.org/soap/envelope/, but got http://www.w3.org/2003/05/soap-envelope </faultstring></S:Fault></S:Body></S:Envelope>'
Then, we changed the bindings as below
<system.serviceModel>
<bindings>
<wsHttpBinding>       
<binding
name="ObjectServicePortBinding1">
<security
mode="Transport">
<transport
clientCredentialType="Certificate"
proxyCredentialType="None"
realm=""
/>
<message
clientCredentialType="Certificate"
algorithmSuite="Default"
/>
</security>
</binding>
<binding
name="QueryServicePortBinding">
<security
mode="Transport">
<transport
clientCredentialType="
Certificate"
proxyCredentialType="None"
realm=""
/>
<message
clientCredentialType="Certificate"
algorithmSuite="Default"
/>
</security>
</binding>
</wsHttpBinding>
</bindings>
We are getting another error message,
Exception: The client certificate is not provided. Specify a client certificate in ClientCredentials.
Any pointers on resolving this issue would be highly helpful.
Thanks

Hi Dhanasegaran,
  As per your case, the corresponding details which may guide you to resolve this issue:
1. First of all, you can try to call the wcf service directly from the browser & check where it will point out the correct location.
2. In config file ,Set IncludeExceptionDetailInFaults to true to enable exception information to flow to clients for debugging purposes .
Set this to true only during development to troubleshoot a service like below :
<serviceBehaviors>
  <behavior name="metadataAndDebugEnabled">
    <serviceDebug
      includeExceptionDetailInFaults="true"   
/>
    <serviceMetadata
      httpGetEnabled="true"
      httpGetUrl=""   
/>
  </behavior>
</serviceBehaviors>
3. I suggest you to change that <security mode ="TransportWithMessageCredential"> instead of <security mode ="Transport">
