settingspane in windows store apps

OPen App.xaml.cs page and follow the below steps.

First thing you should do is to add callisto reference to your app or project references node and the namespaces shown below in bold and underlined.
Then you add two usercontrols to your project. In this code I named two usercontrols  as AboutUserControl and  PrivacyPolicyUserControl.
Then add the following code which highlighted in bold underlined.


using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using Windows.ApplicationModel;
using Windows.ApplicationModel.Activation;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
using Windows.UI;
using Windows.UI.ApplicationSettings;
using Callisto.Controls;

// The Blank Application template is documented at http://go.microsoft.com/fwlink/?LinkId=234227

namespace CountryInformation
{
    /// Provides application-specific behavior to supplement the default Application class.
    sealed partial class App : Application
    {
        /// Initializes the singleton application object.  This is the first line of authored code
        /// executed, and as such is the logical equivalent of main() or WinMain().
        ///
        public App()
        {
            this.InitializeComponent();
            this.Suspending += OnSuspending;
        }
        private Color _background = Color.FromArgb(255, 24, 0, 82); 
        /// Invoked when the application is launched normally by the end user.  Other entry points
        /// will be used when the application is launched to open a specific file, to display
        /// search results, and so forth.
        ///
        /// Details about the launch request and process.
        protected override void OnLaunched(LaunchActivatedEventArgs args)
        {
            Frame rootFrame = Window.Current.Content as Frame;

            SettingsPane.GetForCurrentView().CommandsRequested += OnCommandsRequested;


            // Do not repeat app initialization when the Window already has content,
            // just ensure that the window is active
            if (rootFrame == null)
            {

                rootFrame = new Frame();

                if (args.PreviousExecutionState == ApplicationExecutionState.Terminated)
                {
                    //TODO: Load state from previously suspended application
                }

                Window.Current.Content = rootFrame;
            }

            {
                // When the navigation stack isn't restored navigate to the first page,
                // configuring the new page by passing required information as a navigation
                // parameter
                if (!rootFrame.Navigate(typeof(MainPage), args.Arguments))
                {
                    throw new Exception("Failed to create initial page");
                }
            }
            // Ensure the current window is active
            Window.Current.Activate();
        }
