Downloading PDC10 videos using the new async feature

I knew PDC10 has an OData endpoint which is . The best part about  OData is querying for specific data that we are looking for. And here is my OData url for filtering twitter hashtag #languages$filter=startswith(TwitterHashtag,'%23languages')&$expand=DownloadableContent&$select=DownloadableContent

With the above OData feed I could get urls for low bandwidth mp4’s that I can download. And here is the sample code for filtering

var x =XDocument.Load(@"c:tempsession.xml").Descendants().AsParallel().Where(xd => xd.Name.LocalName=="Url"
&& xd.Value.Contains("_Low.mp4")).Select (xd => xd.Value);

Now that I have the url’s ,here is the code to download the videos using the new async feature

using System;
using System.IO;
using System.Linq;
using System.Net;
using System.Threading.Tasks;
using System.Xml.Linq;

namespace Test
 class Foo
 static void Main(string[] args)
 static async void DownloadAsync()
 var result = new WebClient().DownloadStringTaskAsync("$filter=startswith(TwitterHashtag,'%23languages')&$expand=DownloadableContent&$select=DownloadableContent");
 var downloads = XDocument.Parse(await result).Descendants().AsParallel().
 Where(xd => xd.Name.LocalName == "Url" && xd.Value.Contains("_Low.mp4")).
 Select(xd => new WebClient().DownloadFileTaskAsync(xd.Value, Path.GetFileName(xd.Value)));
 await TaskEx.WhenAll(downloads).ContinueWith(_ => Console.WriteLine("Downloading Complete"));
