비하인드 코드

    /// </summary>
    public partial class MainWindow : Window
    {
      

        public MainWindow()
        {
            InitializeComponent();
          
            xMainFrame.Navigate(new GreenPage());
        }

        private void xButtonGreen_Click(object sender, RoutedEventArgs e)
        {
           
            xMainFrame.Navigate(new GreenPage());

        }

        {
           
            xMainFrame.Navigate(new YellowPage());

        {

    }
}

Page 새로 안만들게하기

계속 new 키워드를 이용해 page를 변경할때마다 새로운 page가 생성된다면 메모리 낭비가 심해질수있다 . 최적화를 위한 조치를 생각해보자
