## Windows Phone 应用的功能和硬件要求  ##

在获取设备硬件信息之前，你还**需要在清单文件中标记你的应用需要的功能（CAPABILITIES）**。另外你还**可以在清单文件中指定应用的硬件要求（REQUIREMENTS），以确保只有满足硬件要求的设备才能在应用商店中查看并下载安装你的应用**。

要了解应用功能和硬件要求，可以在下面链接查看： [ http://msdn.microsoft.com/zh-cn/library/windowsphone/develop/jj206936.aspx][http_msdn.microsoft.com_zh-cn_library_windowsphone_develop_jj206936.aspx]

### 应用清单文件  ###

文件路径：工程目录->Properties->WMAppManifest.xml

### 应用清单文件设计器(Windows Phone 8)  ###

[![Hardware Finder 3.png][]][Hardware Finder 3.png 1]

[![Hardware Finder 4.png][]][Hardware Finder 4.png 1]

我们可以通过清单文件设计器来标记应用的功能和硬件要求，但是在设计器中不能够标记全部的功能或硬件要求（比如ID\_REQ\_MEMORY\_300），这时你就需要用“查看代码”的方式打开WMAppManifest.xml文件进行编辑。
