Hello!

I have begun the conversion from Windows 8.1 to Universal apps for some off my application.I have noticed that MS does not support WCF soap on Windows Phone, and therefore i have converted mye Services to REST.

I have been successfull in implementing REST on a operationcontract with a reference type object, but i have not been successfull on the complex type operation.

WCF configuartion:

[WebInvoke(Method ="POST", UriTemplate = "/nySmerteEntitet/", RequestFormat =WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,BodyStyle=WebMessageBodyStyle.Wrapped)]
       [OperationContract]
       _02_DataClasser.SmerteEntitet nySmerteEntitet(_02_DataClasser.SmerteEntitet ent);

Client configuration:

var url = "http://" + valgtServer + "/ServiceIC.svc/nySmerteEntitet/";

            var ent = new SmerteEntitet();
            ent.BrukerId = DataModel.cStatic.Instance.BrukerId;
            ent.Tidspunkt = DateTime.Now;
            ent.YVerdi = verdi;

            var jsonString = ServiceIC.Serialization.Serialize(ent);

            HttpClient httpClient = new System.Net.Http.HttpClient();

            HttpContent contentPost = new StringContent(jsonString, Encoding.UTF8, "application/json");

            HttpResponseMessage response = await httpClient.PostAsync(url, contentPost);

            if (!response.IsSuccessStatusCode)
                throw new Exception("Error while maintaining entites");

            string data = await response.Content.ReadAsStringAsync();

Server implenetation:

public _02_DataClasser.SmerteEntitet nySmerteEntitet(_02_DataClasser.SmerteEntitet ent)
       {

           if (ent == null)
               throw new Exception("S: Entity was null");
           var ta = new SmerterTableAdapter();
           var dt = new dsIC.SmerterDataTable();

           var dr = dt.NewSmerterRow();
           dr.BrukerId = ent.BrukerId;
           dr.Tidspunkt = ent.Tidspunkt;
           dr.Verdi = ent.YVerdi;

           ta.Update(dr);

           return new _02_DataClasser.SmerteEntitet(dr);
       }

When i try the code the server breaks on "throw new Exception("S: Entity was null");"

I have examined the client side and the json string seems legit.

I have seached the web for a solution and since this uses the WinRT namespace the PostAsJsonAsync does not exist on httpclient.

I would be very happy if i can get some information on how to solve this. Kind regards, Eirik
