 Now we can navigate to `/api/Contacts` and see all of the Contacts in the database.  We can filter for a specific Contact by navigating to `/api/Contacts/1` to get just the first contact returned.  We can also post to `/api/Contacts` and add a new Contact to the database. Since there are multiple `DbSet`, you can make the same calls to `/api/Addresses`.
