title: Use timer on Windows Phone application
body: <p>How to create a timer for c# windows phone 7?
  I already find a timer, but it was for normal c#, and on C# for windows phone we can´t use system.Timers!I want to play the video just from 5000ms.</p>
  
  <p>This is my code:</p>
  
  <p>using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
              {
                  IsolatedStorageFileStream isoFileStream = myIsolatedStorage.OpenFile("xml_file.xml", FileMode.Open);</p>
  
  <pre><code>            XElement xml = XElement.Load(isoFileStream);
  
                      foreach (XElement node2 in xml.Element("graphics").Elements("file"))
                      {
  
  
  
                          string url_graficos = node2.Element("fileurl").Value;
  
                          string[] array = url_graficos.Split('/');
                          string[,] resultadosImage = { { node2.Element("fileurl").Value, node2.Element("playtime").Value, node2.Element("transition").Value } };
  
                          mediaSound.Play();
                          mediaSound.Stop();
  </code></pre>
