How do I return Json serialized data from WCF?

Question

I have looked and around and seen that it is possible to return objects serialized into Json from a WCF web service. Does anyone know how I can do this?

Thanks

Make sure your requesting client is sending the "Accept: application/json" header? — Randy James, Jul 15 '13 at 20:55

You will have to add attribute to the service like this

    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    ObjectName YourMethodName();

Yes it is possible you can set automaticFormatSelectionEnabled to true standardEndpoint of webHttpEndpoint in web.config like

<webHttpEndpoint>
  <standardEndpoint name="" helpEnabled="true" automaticFormatSelectionEnabled="true"/>
</webHttpEndpoint>

And you need to add http header for json response to your client

using (HttpClient client = new HttpClient("endpoint"))
{
     HttpRequestMessage request = new HttpRequestMessage("GET", "SomeMethod");                
     request.Headers.Accept.AddString("application/json");
    ...
}

Can you provide a tutorial for this or link? – Funky Jul 16 '13 at 08:53 — Funky, Jul 16 '13 at 08:53
