[UWP] VS 2015 xaml设计器的问题 [英] [UWP]Problem with VS 2015 xaml designer
问题描述
我正在开发的计算机用作Windows 7 Pro，但最近已升级到Windows 10 Pro。我目前安装了Visual Studio 2015 Pro。最近我研究了为Windows 10开发通用Windows应用程序并成功启动Visual C＃Universal（空白应用程序）项目
之后（没有任何错误）我无法打开MainPage.xaml的设计器页面（或任何其他视图，如果我添加另一个）。我得到一个"未处理的异常已经发生"错误，包含以下详细信息。
The computer I am developing on use to be Windows 7 Pro, but has since recently been upgraded to Windows 10 Pro. I currently have Visual Studio 2015 Pro installed. Recently I have looked into developing a Universal Windows App for Windows 10 and after successfully starting a Visual C# Universal (Blank App) project (without any errors) I cannot open the MainPage.xaml's designer page (or any other view if I add another). I get a "An Unhandled Exception has occurred" error with the following details.
System.UnauthorizedAccessException
访问被拒绝。
错误0x80070005 ：从位置打开文件：AppXManifest.xml失败并显示错误：访问被拒绝。
System.UnauthorizedAccessException
Access is denied.
error 0x80070005: Opening file from location: AppXManifest.xml failed with error: Access is denied.
现在我查看了AppXManifest.xml文件并看到它拥有System user和my的完全权限帐户。我不确定是什么原因引起了这个问题。我可以看到XAML代码，而不是设计师视图。
Now I have looked at the file AppXManifest.xml and seen that it has full permission's for System user and my account. I am not sure what could be causing the issue. I can see the XAML code, just not the designer view.
任何人都对我可以尝试的东西有任何想法吗？
Any body have any thoughts to what I can try?
我有尝试，删除和创建不同目录和不同驱动器号位置的新项目。我已经尝试修复甚至卸载并重新安装Visual Studio但问题仍然存在。
I have tried, deleting and creating a new project in both different directory and different drive letter location. I have tried repairing and even uninstalling and reinstalling Visual Studio but the problem still happens.
谢谢，
Andy
