Remarks
This interface is a Managed Extensibility Framework (MEF) service that can be imported by a MEF component. Given an IVsHierarchy and an itemid (just a UINT representing a “key” to one of the items in the hierarchy), the IVsHierarchyItemManager can return an IVsHierarchyItem or IVsHierarchyItemIdentity representing that item.
