WPF MVVM C＃：拖放没有代码的列表框

Question

I'm trying to figure out how to reorder the listbox without any code behind. I tried following this post: WPF C#: Rearrange items in listbox via drag and drop It definitely works, but I want to do it with ICommand or AttachBehavior.

Any suggestion? How to hook the Drop and PreviewMouseLeftButtonDownEvent with AttachBehavior?

The Listbox's ItemsSource is a Observable Collection.

<ListBox lib:DragAndDrop.DragEnabled="true"/> // Source
<ListBox lib:DragAndDrop.DropEnabled="true"/> // Target
