I have to write an application in specific language base on its computer locale. But I have no idea how to get LCID or system locale in sandbox environment.
In desktop app, I use this to get info, Does Metro have something similar to this ? Any idea ?

WqlObjectQuery objectQuery = new WqlObjectQuery("select * from win32_OperatingSystem");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(objectQuery);
foreach (ManagementObject MO in searcher.Get())
{
    string locale = MO["locale"] + string.Empty;
}
