First add a label and timer to a form :

timer Properties :
this.timer1.Enabled = true;
this.timer1.Interval = 1000;
this.timer1.Tick += new System.EventHandler(this.timer1_Tick);

declare this globally :
private int hh;
private int mm;
private int ss;

In form_Load event add :

private void Form1_Load(object sender, EventArgs e) { int hours = 360 / 60; int minutes = 360 % 60;

        hh = hours;
        mm = minutes;
        ss = 59;

}

In timer_tick event add this code:

        String Hours;
        String Minutes;
        String Seconds;
        ss = ss - 1;

        Hours = (hh < 10) ? "0" + hh.ToString() : hh.ToString();
        Minutes = (mm < 10) ? "0" + mm.ToString() : mm.ToString();
        Seconds = (ss < 10) ? "0" + ss.ToString() : ss.ToString();
        label1.Text = Hours + " : " + Minutes + " : " + Seconds;

        if (Seconds == "00" && Minutes == "00" && Hours == "00")
        {
            timer1.Enabled = false;
            this.Enabled = false;
            Application.Exit();
        }
        if (ss == 0 && mm == 0)
        {
            ss = 60;
            mm = 59;
            hh = hh - 1;
        }

It seems really resource intensive to go back to the server every second. I would recommend doing something in javascript and using the SetTimeout call. If you're that bent of using managed code though, put a little Silverlight control in the page that has a timer and updated the dom every second.

However you implement the timer, place the countdown display (a label, etc.) inside of an Ajax UpdatePanel control. That way the countdown display can be updated continuously without updating the entire page.
