<GrID x:name="LayoutRoot" Background="White">    <!-- Just a TextBlock to show the output of the timer. -->    <TextBlock Loaded="StartTimer" x:name="myTextBlock" /></GrID>

C#:

public voID StartTimer(object o,RoutedEventArgs sender){    System.windows.Threading.dispatcherTimer mydispatcherTimer = new System.windows.Threading.dispatcherTimer();    mydispatcherTimer.Interval = new TimeSpan(0,100); // 100 Milliseconds     mydispatcherTimer.Tick += new EventHandler(Each_Tick);    mydispatcherTimer.Start();}// A variable to count with.int i = 0;// Fires every 100 miliseconds while the dispatcherTimer is active.public voID Each_Tick(object o,EventArgs sender){     myTextBlock.Text = "Count up: " + i++.ToString();}
