Every time you navigate to a Page, you create a new instance of Page, but the previous Page is not disposed (even if the Page is already in the navigation stack).

To prevent multiple allocation of same page, set NavigationCacheMode="Enabled" attribute to the Page.

Also, to minimize the memory allocation, you must override method OnNavigatedTo and OnNavigatedFrom.

In OnNavigatedTo method:

• Instantiate all memory intensive object or resources
• Add all events handlers you need

• Remove references from all heavy objects
• Remove all events handlers
• Only if you really need, call GC.Collect()
