You seem to be fixated at knowing what objects consist of and you seem to stop at a fairly arbitrary level - primitives provided by the language (int, string etc). Why not go all the way down to bits? I find that a well designed Value object [0] makes me more productive because I specifically don't need to know how it is implemented internally, only the exposed interface. Examples: ZonedDateTime PhoneNumber SocialSecurity Guid EmailAddress Point Url ExpiredCoupon Regarding one specific place, if I only need to know date time and its zone in one specific place, would you recommend Tuple<int, int, int, int, int, int, int, string> instead of ZonedDateTime?
