Question: I created WCF service and testing WCF client using stand alone application. I was able to view this service using Internet Explorer also able to view in Visual studio service references. Here is the error message.

`"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)."`

Could you please advice what could be wrong?

Thank you.

Answer: 
This may be helpful, check the url rewrite rules in ISS 7. This issue will occur if is you didn't configure rule properly.
text/html is SOAP 1.1 header and Content-Type: application/soap+xml is SOAP 1.2
Verify your bindings and return header.
It should be same either 1.1 or 1.2
