Frame.GoBack minimizes the Application

Question

public Constructor1()
{
    this.NavigationCacheMode = NavigationCacheMode.Enabled;
}

....

public Constructor2()
{
    this.NavigationCacheMode = NavigationCacheMode.Enabled;
    HardwareButtons.BackPressed += this.MainPage_BackPressed;
}

private void MainPage_BackPressed(object sender, BackPressedEventArgs e)
{
    if(this.Frame.CanGoBack)
    {
        this.Frame.GoBack();
    }
}

After I use the BackButton on my Windows Phone my Application minimizes itself. I have to go to the Task Manager and click on it to bring it back up. Any suggestions why Frame.GoBack minimizes the Application?

From which page are you pressing the back button, are there other pages below it in the stack? — Prasanna Aarthi, Sep 17 '14 at 13:48
I only have those 2 Pages! The first page is no WebView, if it matters. I Navigate to the seconde Page which invokes a html file I've unpacked before and loads it into the WebView. When i press BackButton it minimizes the Application, but i can open the Application on Page one with help of the task manager. So it does GoBack, but it minimizes the page in the progress — B.

Gosh! I am so sorry... I just forgot to set the e.Handled Property true. — B. Kemmer, Sep 18 '14 at 06:46

private void MainPage_BackPressed(object sender, BackPressedEventArgs e)
{
    if(this.Frame.CanGoBack)
    {
        e.Handled = true;
        this.Frame.GoBack();
    }
}

e.Handled = true; was the problem.
