title: CountDown timer in windows phone
body: <p>How can I implement a countdown timer in my Windows Phone 8.1 app? There seems to be no information available for it. All I could find works for either a Windows Forms application or a Windows Application, but none of them seems to be working on the phone app.This is what I am doing-</p>
  
  <pre><code>namespace Timer
  {
      public partial class MainPage : Page
      {           
          DispatcherTimer mytimer = new DispatcherTimer();
          int currentcount = 0;
          public MainPage()
          {
              InitializeComponent();
  
              mytimer = new DispatcherTimer();
              mytimer.Interval = new TimeSpan(0, 0, 0, 1, 0);
              mytimer.Tick += new EventHandler(mytime_Tick);
                //HERE error comes Cannot implicitly convert type System.EventHandler to System.EventHandler&lt;object&gt;
          }
  
          private void mytime_Tick(object sender,EventArgs e)
          {
              timedisplayBlock.Text = currentcount++.ToString();    
          }
  
          private void startButton_Click(object sender, RoutedEventArgs e)
          {
              mytimer.Start();
          }
      }
  }
  </code></pre>
  
  <p>But it gives me this error-
  <code>Cannot implicitly convert type System.EventHandler to System.EventHandler&lt;object&gt;</code></p>
