Get HttpWebResponse asynchronously for windows phone 8, or anything really, but I needed it for windows phone 8

GetResponseAsyncExtension

public static Task<HttpWebResponse> GetResponseAsync(this HttpWebRequest request)
        {
            var taskComplete = new TaskCompletionSource<HttpWebResponse>();
            request.BeginGetResponse(asyncResponse =>
            {
                try
                {
                    HttpWebRequest responseRequest = (HttpWebRequest)asyncResponse.AsyncState;
                    HttpWebResponse someResponse = (HttpWebResponse)responseRequest.EndGetResponse(asyncResponse);
                    taskComplete.TrySetResult(someResponse);
                }
                catch (WebException e)
                {
                    HttpWebResponse failedResponse = (HttpWebResponse)e.Response;
                    taskComplete.TrySetResult(failedResponse);
                }
            }, request);
            return taskComplete.Task;
        }
