I am having difficulty in making my WCF service JSON content. Here is a simple repro where I am expecting the response to be JSON and the service is returning XML.
I have decorated the ResponseFormat with JSON. The client has also set the Accept header as application/json.
[WebInvoke(UriTemplate = "Add", Method = WebRequestMethods.Http.Post, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Wrapped)]
public int Add(int i)

POST http://XXXX/Add HTTP/1.1
Content-Type: application/xml; charset=utf-8
