How can a class provide it's users with named constants, enums, types, structs and not just member functions? |

Just declare them inside the class. They then go inside the class namespace, but are not strictly part of the class instance itself.
e.g.:
class C
{
enum Enum { one, two, three}
struct S { int x; int y; }
}
C.Enum e = C.Enum.one;
C.S s = C.S(1, 2);
// can also access the namespace via an instance:
C instance;
instance.Enum e = instance.Enum.one;
