the content type 'application/json; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'

Question

When using firebug, I got this wired error \"NetworkError: 415 Cannot process the ...xt/xml; charset=utf-8\'. - http://localhost:59899/wsccc1/wscccService.svc/RunTts

Answer 1

Go to your web.config endpoint tag and check if bindingConfiguration is properly present or not and also make sure the address is spelled correctly.

<endpoint address="/YourName".../>

Answer 2

You need to use the WebServiceHostFactory, instead of the regular ServiceHostFactory in your code. That will configure the endpoint with the appropriate binding (webHttpBinding) and behavior (webHttp) to honor the [WebInvoke] attribute.

<serviceHostingEnvironment >
   <serviceActivations>
     <add factory="System.ServiceModel.Activation.WebServiceHostFactory"
          relativeAddress="./wsccc1/wscccService.svc" 
          service="service.wservice"/>
  </serviceActivations>
</serviceHostingEnvironment>
