Create a dispatcher timer and for every ticks update your textbock.

number = 0
dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,0,1);
dispatcherTimer.Start();

private void dispatcherTimer_Tick(object sender, EventArgs e)
{
    //if you use binding and mvvm
    this.Text = number.tostring();
    //if you don't use binding
    yourTextblock.Text = number.toString();
    number ++;
 }
