I am trying to implement a Timer in windows phone app.It works fine in Windows Phone App(Silverlight) but it isnt working in Windows Phone Blank App.But it gives me following error-

Cannot implicitly convert type System.EventHandler to System.EventHandler<object>

This is my code -

namespace Timer
{
    public partial class MainPage : Page
    {           
        DispatcherTimer mytimer = new DispatcherTimer();
        int currentcount = 0;
        public MainPage()
        {
            InitializeComponent();

            mytimer = new DispatcherTimer();
            mytimer.Interval = new TimeSpan(0, 0, 0, 1, 0);
            mytimer.Tick += new EventHandler(mytime_Tick);
              //HERE error comes Cannot implicitly convert type System.EventHandler to System.EventHandler<object>
        }

        private void mytime_Tick(object sender,EventArgs e)
        {
            timedisplayBlock.Text = currentcount++.ToString();    
        }

        private void startButton_Click(object sender, RoutedEventArgs e)
        {
            mytimer.Start();
        }
    }
}

I tried Cannot implicitly convert type 'System.EventHandler' to 'System.EventHandler<object>' for storyboard complete

But it even helped.How can I fix this error?
