I have seen the same problem on w8.1 with printingInline using charmBar it's consuming a lot of memory until crash of the application (1.5 GB). but normaly you don't need GC.colect() it's work automaticly .

Answer 2

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
• starts all timers, tasks or threads

In OnNavigatedFrom:

• Dispose all resources
• Stops all timers, tasks or threads
• Remove references from all heavy objects
• Remove all events handlers
• Only if you really need, call GC.Collect()

Can we see your xaml code? Are you using x:name in your xaml and is that being destroyed? If so that might cause your memory leak.

Look at this link if you are using x:name: http://support.scichart.com/index.php?/News/NewsItem/View/21/wpf-xname-memory-leak--how-to-clear-memory-in-scichart

Of course a UWP may handle x:name differently...
