如图所示,第一次加载会展示新特性.
以后直接转到主页面.
很简单.上代码.

/// <summary>
    /// 应用主页面
    /// </summary>
    public partial class MainPage : PhoneApplicationPage
    {
        // 构造函数
        public MainPage()
        {
            InitializeComponent();
             
        }
        protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
        {
              
             if (WPHelper.IsFirstStart())
            {//如果是第一次加载,跳到特性展示页面.
                NavigationService.Navigate(new Uri("/NewFeaturesShow/PanoramaPage1.xaml", UriKind.Relative));
            }
        }
    }

public class WPHelper
{
    /// <summary>
    /// 是否第一次启动
    /// </summary>
    /// <returns>true 为第一次启动</returns>
    public static bool IsFirstStart()
    {
        IsolatedStorageSettings userSetting = IsolatedStorageSettings.ApplicationSettings;
        try
        {
            string isFirstStart = userSetting["isFirstStart"] as string;
            if (isFirstStart == "1")
            {
                return true;
            }
            else
            {
                return false;
            }
        }
        catch (System.Collections.Generic.KeyNotFoundException)
        {
            userSetting.Add("isFirstStart", "0");
            return true;
        }
 
 
 
    }
 
}
