Error while invoking WCF web service

Question

I have referenced WCF service in class library and that class library in a web application. When I tried to invoke a method from the service I am getting below exception.

"Content Type multipart/related; type="application/xop+xml";start="<http://tempuri.org/0>";boundary="uuid:901bc2e6-6d57-4363-9f99-41ca4884ce16+id=1";start-info="text/xml" was not supported by service https://URL_OF_Service/.  The client and service bindings may be mismatched."

Here is my configurations

<system.serviceModel>
    <bindings>
      <customBinding>
        <binding name="CoreSoapBinding">
          <textMessageEncoding messageVersion="Soap12" />
          <httpTransport />
        </binding>
      </customBinding>
    </bindings>
    <client>
      <endpoint address="https://URL_OF_Service/" binding="customBinding"
          bindingConfiguration="CoreSoapBinding" contract="ContractName"
          name="CoreSoapPort" />
    </client>
  </system.serviceModel>

And I created binding object in the application and passed to the service.

BasicHttpBinding binding = new BasicHttpBinding()
            binding.Security.Mode = BasicHttpSecurityMode.Transport;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
            binding.Name = "CoreSoapPort";
            binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
            binding.BypassProxyOnLocal = false;
            binding.UseDefaultWebProxy = true;
            binding.MessageEncoding = WSMessageEncoding.Mtom;
            binding.AllowCookies = false;
            binding.TransferMode = TransferMode.Buffered;
            binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
            Encoding textencoding = Encoding.UTF8;
            binding.TextEncoding = textencoding;
            binding.MaxReceivedMessageSize = Int32.MaxValue;

I tried changing the configuration to multiple to match the server configuration. But no luck.

The error message is saying mtom content type (multipart/related) isn't supported by the service. Why do you think you need to specify mtom in your binding configured by code? — MattC, Oct 08 '15 at 19:17

Have you tried to change your message encoding configuration to MTOM? IMHO, I think you should not used both configuration file and programmatically to configure your WCF service because it will give you a lot of headache. I suggest to stick to one, it's either configuration file or programmatically.

In the above code I have mentioned this. binding.MessageEncoding = WSMessageEncoding.Mtom; – Pradeep Oct 05 '15 at 08:33
I didn't mention that is should be in configuration file. – jtabuloc Oct 05 '15 at 08:36
I have the latest configurations as – Pradeep Oct 05 '15 at 08:48
Your latest configuration has semi-colon after URL_OF_Service? It that a typo I guest. – jtabuloc Oct 05 '15 at 08:56
That is a typo. Sorry – Pradeep Oct 05 '15 at 09:11

The error happens because of binding mismatch. You server binding is a BasicHttpBinding, and your client is a CustomBinding.

As your service are using BasicHttpBinding, try to configure your client with same binding, but, if you want to use Soap12, you will need to configure your server side as CustomBinding, something like this:

CustomBinding binding = new CustomBinding();
            SymmetricSecurityBindingElement ssbe =
                SecurityBindingElement.CreateSspiNegotiationBindingElement(true);
            // Add the SymmetricSecurityBindingElement to the BindingElementCollection.
            binding.Elements.Add(ssbe);
            binding.Elements.Add(new TextMessageEncodingBindingElement());
            binding.Elements.Add(new HttpTransportBindingElement());
