Is there any way to await an IAsyncResult in Windows Phone 8?

Solution
Use `TaskFactory.FromAsync` to create a `Task<Stream>` from the `BeginGetRequestStream`/`EndGetRequestStream` methods. Then you can get rid of your `OnGotWebRequest` completely, and do the same thing for the response.
Note that currently you're calling `EndGetResponse` when a `BeginGetRequestStream` call completes, which is inappropriate to start with - you've got to call the `EndFoo` method to match the `BeginFoo` you originally called. Did you mean to call `BeginGetResponse`?

How can I use await with HttpWebRequest in Windows Phone 8 ? Is there a way to make the IAsyncResult stuff work with await? ``` private async Task<int> GetCurrentTemperature() { GeoCoordinate location = GetLocation(); string url = "http://free.worldweatheronline.com/feed/weather.ashx?q="; url += location.Latitude.ToString(); url += ","; url += location.Longitude.ToString(); url += "&format=json&num_of_days=1&key=MYKEY"; HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url); webRequest.Method = "POST"; webRequest.BeginGetResponse(new AsyncCallback(OnGotWebRequest), webRequest); } private void OnGotWebRequest(IAsyncResult asyncResult) { HttpWebRequest webRequest = (HttpWebRequest)asyncResult.AsyncState; var httpResponse = (HttpWebResponse)webRequest.EndGetResponse(asyncResult); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { string responseText = streamReader.ReadToEnd(); } } ``` Thanks!
