Windows phone 7之hello world
我安装的是Windows Phone 7.1SDK，另外安装了前几天新出的7.1.1更新(对初学者无所谓)。首先打开Microsoft Visual Studio 2010 Express for Windows Phone 7.1 – ENU，新建一个C#类型的windows phone项目，选择Windows Phone Application，项目名字为“HelloWorld”选择一个路径，选择OK，然后选择7.1类型的系统，OK，创建项目成功了。项目结构如下图
可以看到，创建项目的同时会默认的创建一个结局方案，并将项目包含在解决方案之下，解决方案和项目名称是一样的（7.0版本默认不会创建解决方案）。下面对项目中的文件做一个说明：
App.xaml / App.xaml.cs
定义应用程序的入口点，初始化应用程序范围内的资源,，显示应用程序用户界面
MainPage.xaml / MainPage.xaml.cs
定义应用程序中的程序页面（程序默认主页面，可以修改默认主页面，下面会说明如何修改）
ApplicationIcon.png
一种带有图标的图像文件（不能是gif格式），代表了手机应用程序列表中应用程序的图标
Background.png
一种带有图标的图像文件，代表了在开始页面上应用程序的图表
SplashScreenImage.jpg
这个图片会在应用程序启动时显示。
Properties\AppManifest.xml
一个生成应用程序包所必需的应用程序清单文件
Properties\AssemblyInfo.cs
包含名称和版本的元数据，这些元数据将被嵌入到生成的程序集
Properties\WMAppManifest.xml
一个包含与Windows Phone Silverlight应用程序相关的特定元数据的清单文件，且包含了用于Windows Phone的Silverlight所具有的特定功能，可以根据需要对此文件进行修改
References folder
一些库文件（集）的列表，程序集的引用会在此显示
App.xaml / App.xaml.cs
Launching方法在项目启动时触发，Closing在程序关闭时触发，Activated在程序激活时触发，Deactivated在项目挂起时触发（比如切换到其他程序界面）

ProductID是程序的唯一标示，Title是程序名，安装后显示的，另外DefaultTask是用来设置程序启动的主页面的默认为MainPage.xaml
MainPage.xaml
上述代码运行效果如下
现在修改代MainPage中的代码
再次运行，效果如下图所示
好了，的内容就到此为止吧，高手不要嫌这篇文章太简单，必须要照顾初学者的
