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.

This may be helpful, check the url rewrite rules in ISS 7. This issue will occur if is you didn't configure rule properly.
It sounds like your application is expecting XML but is receiving plain text. What type of object are you passing in?
