my understanding is that when you assign an entity selection (which is an
object, not collection)
as the data source of a listbox,
a kind of proxy collection is created to bind the entity selection to the UI.
basic features are common ("This" is an object and This.property is a value),
but there are major differences between an entity and a regular object (member
methods, etc)
so not all code can be agnostic, especially if you do more than display data.
