Compare Selected Objects and Their Persistent Reference IDs (VB.NET)
This example shows how to determine if two selected entities are the
same entities and if those entities have the same persistent IDs.
Using IModelDocExtension::IsSamePersistentID
and ISldWorks::IsSame
might be helpful when your application is passed two entities that it
didn't select, and your application needs to know if they're the same
entity.

' Preconditions: A part document is open and two
' different entities (e.g., faces, edges, vertices, etc.)
' are selected.

' Postconditions: None
