XAML Designer 使用 VS2015 RTM 抛出拒绝访问异常

Question

我今天刚刚全新安装了 Windows 10 + Visual Studio 2015，两个都是 RTM。当我创建一个新的 UWP 应用程序并双击 MainPage.xaml 时，设计器立即崩溃。这是堆栈跟踪：

System.Exception
Package could not be registered.

error 0x80070005: While processing the request, the system failed to register the windows.capability extension due to the following error: Access is denied.

   at System.Threading.Tasks.Task`1.InnerInvoke()
   at System.Threading.Tasks.Task.Execute()

我发现 other MSDN 上的帖子看起来具有相似的堆栈跟踪，但错误不同（通常与损坏的包有关）。这些是否适用/是否有其他解决方法？

谢谢。

您必须启用 Windows 10 系统的 "developer mode" 才能启用应用程序开发的调试和设计器。另请参阅此站点：Enable your device for development
