using restsharp with caliburn.micro

[Ville Autio]

Hi,

I'm developing a simple news application for WP7 using Caliburn.Micro. I would like to use Restsharp for rest services.

In my viewmodel I create a new instance of class that uses restsharp.
Then I call LoadData-method in above intance.

Restsharp code is as follows:

            client = new RestClient();
            client.BaseUrl = "http://www.choomba.org/motocross/kisat.txt";
            client.AddHandler("text/plain", new JsonDeserializer());
            Debug.WriteLine("requesting from: " + client.BaseUrl);
            client.CookieContainer = new CookieContainer();
            var request = new RestRequest(Method.GET);
 
            request.AddParameter("rnd", DateTime.Now.Ticks);
 
            request.RequestFormat = DataFormat.Json;
            //request.OnBeforeDeserialization = resp => resp.ContentType = "text/json";
            Debug.WriteLine("kisat webservice execute async");
 
            //var asyncHandle = client.ExecuteAsync(request, Callback);
 
            client.ExecuteAsync(request, response =>
             {
                     RestResponse resourse = (RestResponse)response;
                     Debug.WriteLine(response.ResponseStatus);
             });
 

Problem is that ResponseStatus is always Error.

What gives? What am I doing wrong here?

Br,

What's in response.ErrorException?

Hi,

I get a NullreferenceException.

response.ErrorException
{""}
[System.NullReferenceException]: {""}

_HResult: -2147467261
_innerException: {"NullReferenceException"}
_message: ""

InnerException is as follows:

Surely it can't be this hard?
