Circular reference among two .net assemblies

Question

I have two assemblies A & B.

A has existing reference to B and it must be kept that way. Right now I made some changes to B that need to refer to A. So circular

Answer 1

Sounds like you are attempting death by interface. Not everything has to be exposed by interface.

A simple answer is to either merge the assemblies, or move the common controls and data types to a third assembly. You only need to interface things if you want a consistent contractual way to access or work with things, and you want to hide the actual implementation.
