我正在尝试在 Studio 中将 6.3 项目升级到 7.1，升级不断崩溃并关闭项目。

如果我从我的应用程序中删除 windows8 项目文件，则升级成功。我附上了我的 appx.manifest 文件，以防这有助于调试问题。

10:49:13 AM：[2016-02-09 10:46:18] 将 WLWin8Native 引用和 AuthWinRT.targets 添加到 Windows 8 项目文件 [2016-02-09 10:46:21] FWLST1226I：添加了授权管理器 Cordova config.xml 的插件（C:\Users\IBM_ADMIN\MobileFirst71Prototype\MaximoAnywhere\apps\WorkExecution\iphone\native\config.xml）。

这是我的 package.appxmanifest 文件

不知何故，我的 VisualElements 元素中有一些无效的 XML。一旦我将清单的 VisualElements 部分修复为如下所示，升级就完成了。

 <VisualElements BackgroundColor="#003f69" Description="Inspection" DisplayName="Inspection" ForegroundText="light" Logo="images\logo.png" SmallLogo="images\smalllogo.png" ToastCapable="true">
        <SplashScreen Image="images\splashscreen.png"/>
      </VisualElements>
