Every drag-and-drop operation within a hierarchy requires information about the item dragged and where it is being dropped. IVsHierarchyDropDataSource2 provides the information about the dragged item. The IVsHierarchyDropDataTarget interface provides information about where the item is being dropped.

Notes to Implementers

Hierarchies in VSPackages are most commonly used to display projects. Use this interface within your hierarchy implementation to include drag-and-drop behavior within and between hierarchies.
