问题描述

我刚刚在 Windows 8.1 操作系统上安装了 Visual Studio Express 2013 更新 4，并启动了一个新的 Windows Phone 应用项目.当我尝试打开任何 XAML 的 View Designer 页面时，它失败并显示以下错误消息:

I have just installed Visual Studio Express 2013 update 4 on Windows 8.1 OS, and started a new Windows Phone App project. When I tried to open a View Designer page of any XAML, it fails with the following error message:

System.Exception
Package failed updates, dependency or conflict validation.
Windows cannot install package App.af631a335.af069.a4bf5.a81c7.af4c34f85cb29 because this package depends on another package that could not be found. This package requires minimum version 0.0.0.0 of framework Microsoft.VCLibs.120.00.Debug published by any publisher to install. Provide the framework along with this package.
