I think that we dont need to unsubscribe an event if defined in xaml. if we subscribe named event like that in OnAppearing method of the page
_listView.SelectionChanged += listviewchangedevent;
we need to unsubscribe on OnDissapearing method
_listView.SelectionChanged -= listviewchangedevent;
But what about below usage?
_listView.SelectionChanged += (sender, args) =>
{
// Do something
};
Can this cause a memory cycle?
