Manually updating WPF data

Question

I have a List <Foo> from a non-WPF assembly that I am trying to bind to a binding to WPF <ListBox>. Initially, the list items are displayed correctly, but when I add a new item to the <Foo> list, the list does not add the list item. How can I specify in the list box to relink / update / update data and show a new item?
