How can I implement fading in and out of Added/Removed ListItems

Question

Suppose I have a ListBox bound to an ObservableCollection and I want to animate adding/removing of ListBoxItems eg. FadeIn/Out, SlideD

Answer 1

For me FrameworkElement.Unloaded event doesn't work - the item just disappears instantly. I can hardly believe that years of experience with WPF haven't produced anything prettier, but looks like the only way this can work is a hack described here: Animating removed item in Listbox ?..
