WARNING There is no error checking!

Well I feel like I learned something today, have a read of this article http://blogs.msdn.com/b/pfxteam/archive/2010/11/21/10094564.aspx to learn a better way to handle this :)

using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Mvc;
using Newtonsoft.Json;
namespace DribbbleR.Web.Controllers
{
    public class HomeController : Controller
    {
        private static dynamic shots;
        private HttpClient client = new HttpClient();
        private string url = "http://api.dribbble.com/shots/everyone?per_page=30";

        public Task Index()
        {    if (shots == null)
             shots = Task.Factory.StartNew
                   (() => return DownloadContent();).Unwrap();    
             return shots;
        }
        public Task DownloadContent()
        {    var responseTask = client.GetAsync(url);
             var readTask = responseTask.ContinueWith
                 (t =>
                     {   t.Result.EnsureSuccessStatusCode();
                         return t.Result.Content.ReadAsStringAsync();
                      }
                  ).Unwrap();
            var deserializeTask = readTask.ContinueWith
                  (t => return JsonConvert.DeserializeObjectAsync(t.Result);)
            .Unwrap();
            var viewTask = deserializeTask.ContinueWith
                  (t =>  return this.View(t.Result););
            return viewTask;
        }
    }
}
