A DbSet for the Series isn't needed because the Series entity is not directly referenced through the context.

But it has a one-to-many relationship with ComicBook, which causes it to be included in the conceptual model when ComicBook is referenced on the context. This also causes it to be included in the storage model, and then to be created as a table.

Conceptual model creation is discussed in the Where's Our Data? video starting at about 4 minutes.
