- To enable a page to be cached, set NavigationCacheMode to either Enabled or Required. The difference in behavior is that Enabled might not be cached if the frame's cache size limit (CacheSize) is exceeded, whereas Required always generates an entry no matter the size limit. - Scenario: After the user selects an image on the PictureChooserPage page, ensure that the app navigates back to the PictureSharerMainPage page.
