这就是我所做的！，我重新安装了 Windows 8 SDK，然后我更新了 Visual Studio 并成功了，希望这对每个人都有效！

编辑：

我所做的更新是 Visual Studio 的第一个“服务包”。

现在问题已经解决了。

按照论坛中的建议，这是我所做的：

卸载 WP8 SDK
卸载 Silverlight SDK 和 Rutime 的所有实例。
重新安装 WP8 SDK。

我修复 VS 设计器问题的确切顺序：

卸载所有 WP7 SDK：
重新启动计算机（此步骤后设计器仍然失败）
已卸载 WP8 SDK（可能这里选择修复就够了，但我选择卸载 SDK）
重新启动计算机
安装了 WP8 SDK

设计师现在工作得很好:)

只需安装最新的 Visual Studio 更新，它应该可以工作。您可以通过转到Tools 菜单并选择Extension and Updates来安装它们。Visual Studio 更新应位于产品更新类别中。

这对我有用：未安装的NuGet（因为它的更新不起作用）
