Content Type application/soap+xml; charset=utf-8 was not supported by service. The client and service bindings may be mismatched

This is the error I had encountered when I was configuring wshttpbinding with Azure WCF  Web role as per the steps I mentioned here - http://sanganakauthority.blogspot.in/2014/03/azure-wcf-web-role-with-wshttpbinding.html 

This problem is encountered when metadata endpoint is not configured on WCF web config file. So you need to configure mex endpoint and mark httpGetEnabled as true. 

<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 

And in service behaviour mark httpGetenabled=true. This should solve the problem. 

Hope this helps.

Cheers…

Happy Configuring!!!
