问题 I have set NavigationCacheMode to Required in some pages of my WP 8.1 XAML app. How can I remove a specific page from that? This is not Navigation stack. 回答1: If a page has NavigationCacheMode set to Required , there is currently no way to remove it explicitly.

You can do smething like storing a flag to the settings when your app starts and erasing it when your app exists and check this flag in the background agent. 来源： https:/
