Remarks
An IVsHierarchyItem has an associated IVsHierarchyItemIdentity that defines the IVsHierarchy/item identifier or IVsHierarchy/item identifier pair that represents the item. This interface also lets you get properties like text for the items and to enumerate its child and parent items.
A single item in the Solution Explorer (for example, a C# project node) can actually be composed of two different IVsHierarchy implementations with two different item identifiers. As a specific example, the “solution” is an IVsHierarchy representing the “tree” of items in the solution, but the solution’s IVsHierarchy does not know about the content of projects. A specific C# project in the solution is also a separate IVsHierarchy. The node representing the project itself might be node #50 in the IVsHierarchy for the solution, and node VSITEMID_ROOT in the IVsHierarchy for the project. IVsHierarchyItemIdentity and IVsHierarchyItem bind together these two different IVsHierarchy and item identifiers into a single concept.
