介紹
與眾不同 windows phone 7.5 (sdk 7.1)

• 使用 Silverlight 開發 Windows Phone 應用程序
• 使用 XNA 開發 Windows Phone 應用程序
• 使用 Silverlight 和 XNA 組合開發 Windows Phone 應用程序（在 Silverlight 中融入 XNA）

示例
1、使用 Silverlight 開發 Windows Phone App 的 Demo
MainPage.xaml

<phone:PhoneApplicationPage 
    x:Class="Silverlight.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait" Orientation="Portrait"
    shell:SystemTray.IsVisible="True">

    <StackPanel>
        <!--按鈕-->
        <Button Name="btn" Content="hello webabcd" />
    </StackPanel>
 
</phone:PhoneApplicationPage>

MainPage.xaml.cs

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.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;

namespace Silverlight
{
    public partial class MainPage : PhoneApplicationPage
    {
        public MainPage()
        {
            InitializeComponent();

            this.Loaded += new RoutedEventHandler(MainPage_Loaded);
        }

        void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            // 彈出 MessageBox 信息
            btn.Click += delegate { MessageBox.Show("hello webabcd"); };
        }
    }
}

2、使用 XNA 開發 Windows Phone App 的 Demo
Game1.cs

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Input.Touch;
using Microsoft.Xna.Framework.Media;

namespace XNA
{
    // 啟動時先 Initialize，再 LoadContent，退出時 UnloadContent
    public class Game1 : Microsoft.Xna.Framework.Game
    {
        // 圖形設備（顯卡）管理器，XNA 在游戲窗口上做的所有事情都要通過此對象
        GraphicsDeviceManager graphics;

        // 精靈繪制器
        SpriteBatch spriteBatch;

        // 2D 紋理對象
        Texture2D sprite;

        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);

            // 指定游戲窗口的寬和高，不設置的話會花屏
            graphics.PreferredBackBufferWidth = this.Window.ClientBounds.Width;
            graphics.PreferredBackBufferHeight = this.Window.ClientBounds.Height;

            Content.RootDirectory = "Content";

            // 兩次繪制的間隔時間，本例為每 1/30 秒繪制一次，即幀率為 30 fps。此屬性默認值為 60 fps
            TargetElapsedTime = TimeSpan.FromSeconds(1f / 30);

            // 當禁止在鎖屏狀態下運行應用程序空閑檢測（默認是開啟的）時，將此屬性設置為 1 秒鍾，可減少鎖屏啟動應用程序時的耗電量。此屬性默認值為 0.02 秒
            InactiveSleepTime = TimeSpan.FromSeconds(1);
        }

        /// <summary>
        /// 游戲運行前的一些初始化工作
        /// </summary>
        protected override void Initialize()
        {
            base.Initialize();
        }

        /// <summary>
        /// 加載游戲所需用到的資源，如圖像和音效等
        /// </summary>
        protected override void LoadContent()
        {
            spriteBatch = new SpriteBatch(GraphicsDevice);

            // 將圖片 Image/Son 加載到 Texture2D 對象中
            sprite = Content.Load<Texture2D>("Image/Son");
        }

        /// <summary>
        /// 手工釋放對象，游戲退出時會自動調用此方法
        /// 注：XNA 會自動進行垃圾回收
        /// </summary>
        protected override void UnloadContent()
        {

        }

        /// <summary>
        /// Draw 之前的邏輯計算
        /// </summary>
        /// <param name="gameTime">游戲的當前時間對象</param>
        protected override void Update(GameTime gameTime)
        {
            // 用戶按返回鍵則退出應用程序
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
                this.Exit();

            base.Update(gameTime);
        }

        /// <summary>
        /// 在游戲窗口上進行繪制
        /// </summary>
        /// <param name="gameTime">游戲的當前時間對象</param>
        protected override void Draw(GameTime gameTime)
        {
            // 清除游戲窗口上的所有對象，然后以 CornflowerBlue 顏色作為背景
            GraphicsDevice.Clear(Color.CornflowerBlue);

            // SpriteBatch.Draw() - 用於繪制圖像，其應在 SpriteBatch.Begin() 和 SpriteBatch.End() 之間調用
            spriteBatch.Begin();
            spriteBatch.Draw(sprite, new Vector2((this.Window.ClientBounds.Width - sprite.Width) / 2, (this.Window.ClientBounds.Height - sprite.Height) / 2), Color.White);
            spriteBatch.End();

            base.Draw(gameTime);
        }
    }
}

3、使用 Silverlight 和 XNA 組合開發 Windows Phone App 的 Demo（在 Silverlight 中融入 XNA）

    SupportedOrientations="Portrait" Orientation="Portrait"
    mc:Ignorable="d" d:DesignHeight="800" d:DesignWidth="480"
    shell:SystemTray.IsVisible="False">
    
    <StackPanel Orientation="Vertical">
        
        <!--
            4 個按鈕，用於控制 sprite 的 上/下/左/右 移動
        -->
        
        <Button Name="btnUp" Content="上" Click="btnUp_Click" />
        <Button Name="btnDown" Content="下" Click="btnDown_Click" />
        <Button Name="btnLeft" Content="左" Click="btnLeft_Click" />
        <Button Name="btnRight" Content="右" Click="btnRight_Click" />
    </StackPanel>

</phone:PhoneApplicationPage>
