    SupportedOrientations="Portrait" Orientation="Portrait"
    mc:Ignorable="d" d:DesignHeight="768" d:DesignWidth="480"
    shell:SystemTray.IsVisible="True">

    <phone:PhoneApplicationPage.Resources>
        <!--
            注：AppResources 里的类和构造函数需要 public 的要手动改成 public
        -->
        <resources:AppResources xmlns:resources="clr-namespace:Demo.Resources" x:Key="MyLocalization" />
    </phone:PhoneApplicationPage.Resources>
    
    <Grid x:Name="LayoutRoot" Background="Transparent">

        public TrialExperience()
        {
            InitializeComponent();

            // 检查许可证，仅为测试用，实际项目中最好将此逻辑放到 Application_Launching 和 Application_Activated 中
            CheckLicense();
        }

        private void CheckLicense()
        {
#if DEBUG
            // 仅调试用，强行指定程序为试用版
            _isTrial = true;
#else
            // 获取当前安装到设备的版本是否为试用版
            _isTrial = _licenseInfo.IsTrial();
#endif
            
            // 如果是试用版则禁用正式版的功能
            if (_isTrial)
                btnNormal.IsEnabled = false;
        }

        private void btnTrial_Click(object sender, RoutedEventArgs e)

        {
            MessageBox.Show("正式版里才有的功能");
        }

        private void btnBuy_Click(object sender, RoutedEventArgs e)
        {
            // 购买的话，直接打开应用程序在商店的详细页就好
            MarketplaceDetailTask marketPlaceDetailTask = new MarketplaceDetailTask();
            marketPlaceDetailTask.Show();
        }
    }
}

4、演示如何使用系统主题资源
ThemeResources.xaml

<phone:PhoneApplicationPage 
    x:Class="Demo.Feature.ThemeResources"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        <TextBlock Text="注：不同的应用程序有不同的密钥" />
        
    </Grid>

</phone:PhoneApplicationPage>

EncryptData.xaml.cs

/*
 * 演示如何对数据做加密解密
 * 
 * ProtectedData - 用于加密解密数据
 *     Protect() - 加密数据
 *     Unprotect() - 解密数据
 * 
 * 注：不同的应用程序有不同的密钥，所以本示例的加密解密仅针对同一应用程序有效。应用场景为：本地数据的加密解密
 */

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;

using System.Text;

namespace Demo.Feature
{
    public partial class EncryptData : PhoneApplicationPage
    {
        private string _base64 = "";

        public EncryptData()
        {
            InitializeComponent();

            EncryptDemo();

            DecryptDemo();
        }

        private void EncryptDemo()
        {
            byte[] plainText = Encoding.UTF8.GetBytes("webabcd");
            byte[] protectedData = ProtectedData.Protect(plainText, null);

            _base64 = Convert.ToBase64String(protectedData);

            MessageBox.Show("字符串“webabcd”加密且base64后的数据：" + Environment.NewLine + _base64);
        }

        private void DecryptDemo()
        {
            byte[] protectedData = Convert.FromBase64String(_base64);
            byte[] plainText = ProtectedData.Unprotect(protectedData, null);

            MessageBox.Show("解密后的数据：" + Environment.NewLine + Encoding.UTF8.GetString(plainText, 0, plainText.Length));
        }
    }
}
