Error when dealing with DispatcherTimer.Tick method

Question

I need a simple timer that prints the countdown in a TextBlock in my UWP app. I was suggested to use DispatcherTimer. That's my code.

private void MainButton_Click(object sender, RoutedEventArgs e)
        {
            dispatcherTimer = new DispatcherTimer();
            dispatcherTimer.Tick += DispatcherTimer_Tick;
            dispatcherTimer.Interval = new TimeSpan(1000);
            dispatcherTimer.Start();

        }

        private int Seconds;
        private void DispatcherTimer_Tick(object sender, DispatcherTimer  e)
        {
            Seconds++;
            MainTextBlock.Text = Seconds.ToString();
        }

Anyway, I see this error and I cannot figure it out.

Any help in finding a better solution for my needs is welcome, too.
