Content Type application/soap+xml; charset=utf-8 was not supported by service

I am getting the error below while trying to add WCF service to WCFTestClient. I went through a number of solutions on the web but I couldn't get it to work.

Can someone help me with the issues? I am also providing my config file for service:

Content Type application/soap+xml; charset=utf-8 was not supported by service The client and service bindings may be mismatched. The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8

Code:
