Zrobiłem klasę żądania post, której mogłem użyć ponownie, aby żądania POST były wysyłane do zewnętrznego interfejsu API i zwracać obiekty, które mi wysyłają (JSON):

class PostRequest
    {
        private Action<DataUpdateState> Callback;

        public PostRequest(string urlPath, string data, Action<DataUpdateState> callback)
        {
            Callback = callback;

            // form the URI
            UriBuilder fullUri = new UriBuilder(urlPath);
            fullUri.Query = data;

            // initialize a new WebRequest
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(fullUri.Uri);
            request.Method = "POST";

            // set up the state object for the async request
            DataUpdateState dataState = new DataUpdateState();
            dataState.AsyncRequest = request;

            // start the asynchronous request
            request.BeginGetResponse(new AsyncCallback(HandleResponse),
                dataState);
        }

        private void HandleResponse(IAsyncResult asyncResult)
        {
            // get the state information
            DataUpdateState dataState = (DataUpdateState)asyncResult.AsyncState;
            HttpWebRequest dataRequest = (HttpWebRequest)dataState.AsyncRequest;

            // end the async request
            dataState.AsyncResponse = (HttpWebResponse)dataRequest.EndGetResponse(asyncResult);
            if (dataState.AsyncResponse.StatusCode.ToString() == "OK")
            {
                Callback(dataState); // THIS IS THE LINE YOU SHOULD LOOK AT :)
            }
        }
    }

    public class DataUpdateState
    {
        public HttpWebRequest AsyncRequest { get; set; }
        public HttpWebResponse AsyncResponse { get; set; }
    }
}

metoda Callback pobiera obiekt datastate i przesuwa go do tej funkcji:

    public void LoadDashboard( DataUpdateState dataResponse )
    {
        Stream response = dataResponse.AsyncResponse.GetResponseStream();
        //Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
        //StreamReader readStream = new StreamReader(response, encode);
        //readStream.Close();


        Deployment.Current.Dispatcher.BeginInvoke(() => {
            App.RootFrame.Navigate(new Uri("/Interface.xaml", UriKind.RelativeOrAbsolute));
        });
    }

Nie jestem teraz pewien, jak uzyskać treść odpowiedzi wysłanej do mnie z interfejsu API. Zwraca format json, muszę być w stanie zmapować go do ładnej klasy C # i użyć go do wyświetlania rzeczy w telefonie.

Nie mogę znaleźć przykładu, który nie używa JSON.NET (który nie ma zespołu dla Windows Phone 8)
