.Net dll libraries aren't COM libraries as everything VB6, .Net deliberately moved away from COM. With .Net you reference the local dll assembly and use its objects like any other class object in .Net.
Class libraries are not application projects that are executable by them selves, so I don't understand your wording exactly.
