Nested Assemblies

I have a cod开发者_开发百科e library(Dll_A) that calls another call code library(DLL_B)

DLL_A will be distributed to other applications for use. When I try to use Dll_A it is saying I must have DLL_B in the reference as well.

If there a way to roll up everything into DLL_A and only have to import that?
