在Windows 8.1 （9477或9471
）上开发Metro应用，当页面上使用ToggleSwitch控件，并且程序具有多语言版本（添加了资源文件的本地化），在Control Panel\Clock, Language, and Region\Language中设置primary
language不是系统语言时，使用DeviceInformation.FindAllAsync(DeviceClass.VideoCapture)会出现System.UnauthorizedAccessException 异常。
但是，Windows8.1(9431)之前版本没有上述问题，请问是什么原因？
追加Troubleshooting tips：
If you are attempting to access a file, make sure it is not ReadOnly. Make sure you have sufficient privileges to access this resource.
请问在调FindAllAsync()时访问了什么文件？
简单建一个C# Store App，问题就再现。

工程中必须添加多语言资源文件，Resources.resw可以是空文件。
