[dba-VB] c# - Creating and using a shared module

I have split my solution into two solutions.  However each of those two solutions uses a shared 
project which I call "base objects".  Obviously I want to split that off and then reference that 
solution from both of the main solutions.

I have never done this before.  Any suggestions, tips and tricks, warnings, how to etc.?
