If an assembly is in the GAC, do all assemblies that it calls have to be in the GAC too?

Question

The question says it all.

Answer 1

An assembly in the GAC does not know about the private locations of your private assemblies. It is only aware about the GAC itself. So it can refer to the assemblies that are available in the GAC only

Answer 2

No - the GAC is the place where you place assemblies that you specifically want to be available globally.
