The content type application/xml;charset=utf-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8)

Question

I trying to consume a WCF web service using stand alone application. I am able to view this service using Internet Explorer also able to view in Visual studio service references.

This is the error I am getting

The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8).

How do I change this to use the correct content type?

Here is my config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="G2WebServiceSoap11Binding" />
        </basicHttpBinding>
        <customBinding>
            <binding name="G2WebServiceSoap12Binding">
                <textMessageEncoding messageVersion="Soap12" />
                <httpTransport />
            </binding>
        </customBinding>
    </bindings>
    <client>
        <endpoint address="http://XXX.XX.XX.XX:XX/janus/services/G2WebService.G2WebServiceHttpSoap11Endpoint/"
            binding="basicHttpBinding" bindingConfiguration="G2WebServiceSoap11Binding"
            contract="G2ServiceReference.G2WebServicePortType"
            name="G2WebServiceHttpSoap11Endpoint" />
        <endpoint address="http://XXX.XX.XX.XX:XX/janus/services/G2WebService.G2WebServiceHttpSoap12Endpoint/"
            binding="customBinding" bindingConfiguration="G2WebServiceSoap12Binding"
            contract="G2ServiceReference.G2WebServicePortType"
            name="G2WebServiceHttpSoap12Endpoint" />
    </client>
</system.serviceModel>

here is the stack

Answer 1

It's possible that your WCF service is returning HTML. In this case, you'll want to set up a binding on the service side to return XML instead. However, this is unlikely: if it is the case, let me know and I'll make an edit with more details.

The more likely reason is that your service is throwing an error, which is returning an HTML error page. You can take a look at this blog post if you want details.

tl;dr: There are a few possible configurations for error pages. If you're hosting on IIS, you'll want to remove the <httpErrors> section from the WCF service's web.config file. If not, please provide details of your service hosting scenario and I can come up with an edit to match them.

EDIT:

Having seen your edit, you can see the full error being returned. Apache can't tell which service you want to call, and is throwing an error for that reason. The service will work fine once you have the correct endpoint - you're pointed at the wrong location. I unfortunately can't tell from the information available what the right location is, but either your action (currently null!) or the URL is incorrect.

When I ran into this error, I spent hours trying to find a solution.

My issue was that when I went to save the file I had accidentally hit the key stroke "G" in the web.config. I had a straggler Character just sittings outside, so the web.config did not know how to interpret the improperly formatted data.

Hope this helps.

Just in case...
If you are using SoapUI Mock Service (as the Server), calling it from a C# WCF:

WCF --> SoapUI MockService

And in this case you are getting the same error:

The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8).

Edit your Mock Response at SoapUI and add a Header to it:

In my scenario, this fix the problem.
