asp.net security: I have 3 Dll's

1) Core Objects and Utilities
2) Data Access layer
3) GUI Layer

2 and 3 both have a reference to 1 (the Core Objects and Utilities)
however certain classes in the utilities I want only to be accessible
for 2 (such as the database access).

Any Ideas?

Thank you

John K
