title: Countdown timer using System.Timers.Timer in WPF application
body: <p>I need to show a countdown timer in label in a WPF application. My research have only led me to the <code>System.Windows.Forms.Timer</code> - but since I use WPF I am not able to use it. <code>System.Windows.Forms.Timer</code> includes a <code>Tick</code> event, but <code>System.Timers.Timer</code> don't. </p>
  
  <p>I need a countdown timer where I e.g can set a countdown of X minutes (X is larger than a couple of hundred minutes). A label will display the countdown values in the european standard format <code>HH:MM:SS</code>.</p>
  
  <p>Does anyone have a solution for this?</p>
