由于权限问题，无法启动Designer

Question

我第一次深入研究通用应用程序的世界似乎已经停止了大约2分钟，因为我甚至无法访问设计师。

以前没有发生这种情况，我的所有其他项目（非UWP应用程序）工作正常，设计人员在这些项目中工作正常，但由于某些原因，在这个UWP项目中，由于出现的情况，无法加载XAML Designer是一些相当广泛的许可问题。

我有谷歌这些错误，我发现我无法做任何事情，尽管他是这个非联网计算机上唯一的管理员（实际上是唯一的用户），我无法更改参考装配文件夹的权限（这是在线推荐的。）

我已经发布了以下错误的完整列表，希望有人知道发生了什么，以及我可以做些什么来解决这个问题，以便我可以继续做一些工作：（

当弹出这个时，我被提示更改权限，但是打开的CMD窗口说它已成功更改了它们，显然不是！

Designer could not be started because of a permissions issue on the drive to which it is installed. Please check the permissions of the folder before trying to start the designer.

Answer 1

打开“设置”并检查开发者模式是否未激活

Answer 2

对我来说，打开.xaml文件时会弹出一条消息，询问我是否要提升该文件夹的权限。单击确定会弹出一个黑色命令窗口，在几分钟内似乎没有做任何事情。只是不管它，最终解散了自己，设计师成功加载。
