Remarks
ItemsControl is the base class for containing and displaying one or more data items. ItemContainerGenerator maintains an association between ItemsControl and the list of items that are displayed by ItemsControl. ItemContainerGenerator is also responsible for generating the UI for those items on behalf of ItemsControl. Panel, VirtualizingPanel, and VirtualizingStackPanel also use ItemContainerGenerator for the same reason.
ItemContainerGenerator implements IItemContainerGenerator and is the interface through which each of the mentioned layout elements communicate with ItemContainerGenerator.
