Binding a listbox SelectedItem to an Observable Collection?

Question

I have a Listbox in WPF with the SelectionMode set to Multiple, and can multiselect the items in the Listbox. However, the SelectedItem is not updating the Observable Collection it is bound to.

Is there a way to bind the multiple selected items from a ListBox to an Observable Collection?

I used the method explained here in the duplicate, and that works very well.
