I've been working on a SF Windows project and would now like to build my first SF Web project that uses the same business objects.  I've read the SF Tutorial several times but cannot quite get it to work.

First, can I leave the BO's within the Win solution, or do I need to pull them out as a separate BO library?  I'd prefer to just leave them in the Win project and manage them there.  If this is possible, how do I reference them from the Web project?

On the assumption that I need to pull them out as a separate BO Library (like the Tutorial), I tried this before posting this question.  When I go to add a reference to the new BOL from either the Win or Web solutions, the Add Reference / Project folder is empty (unlike the Tutorial!). 

So I'm stuck at step one of my first SF Web project and must be missing something basic. 

TIA,

Larry
