I have a page where user can enter his name and attach an image.
When returning from tombstoning state, is it mandatory for my app to restore the image too?
Is it app certification requirement, something without which my app will not pass certification? Or is it a recommended pattern?
same question in the case when I have a pivot for example, is it mandatory to save the index of selected pivot item and restore the selection when activating from tombstoning?
Not necessary: Is there a popular library \ framework to help me with tombstoning and serializing objects, images, etc?
