[dotNetRDF-Develop] good to see activity here ... anyone have suggestion for me re:Media Type Formatter

[Steve . <mo...@ho...>]

Anyone else using MVC3 or 4 and processing the 'application/sparql-results+json' media type in a media type formatter .... to return a POCO to the controller ?
I'm able to return the Json in the Controller this way with this code:
var sparqlTask = response.Content.ReadAsStringAsync();
But that requires processing the Json in the controller
Since I could not get the media-formatter working --- the conventional approach threw an exception ... note the highlighted code below that I was not able to get to work ... 
Any members who call Sparql endpoints able to convert json to POCO in a custom media formatter in ASP.Net MVC ???
Thanks,
Steve
Here the hack that I'd like to replace with a MediaFormatter
            var task = client.GetAsync(theURL)                .ContinueWith((taskWithmsg) =>                     {                                    var response = taskWithmsg.Result;                        //var sparqlTask = response.Content.ReadAsAsync<operas>();                        //var sparqlTask = response.Content.ReadAsAsync<SparqlFormatter>();                        var sparqlTask = response.Content.ReadAsStringAsync();                        var sparqlObject = sparqlTask.Result;                        JObject root = JObject.Parse(sparqlObject);                        JArray _operas = (JArray)root["results"]["bindings"];                        sparqlTask.Wait();                       model.AddRange(                             (from JObject jo in _operas                             select new operas                             {                                                                  Opera = jo["Opera"]["value"].ToString(),                                 RingCycleOpera = jo["RingCycleOpera"]["value"].ToString()                             }                          ));                        });            task.Wait();            return View(model);                    }

Subject: [dotNetRDF-Develop] ?? MediaTypeFormatter for	'application/sparql-results+json




I have an ontology on Knoodl that I need to integrate into an ASP.Net MVC4 web application using ReadAsync method of HttpClient ... (webApi using .Net 4.5)
 
How to fix the exception that I get ??  
 
No MediaTypeFormatter is available to read an object of type 'JArray' from content with media type 'application/sparql-results+json
 
 
Pointers to how to add a custom MediaTypeFormatter to my solution, please ... or any other way to get this done ??  Hate to have to resort to XML when Json is an option.
