Two-way communication without a circular reference?

Good evening,

I am building a three-tiered web application in VB.NET 2005, with each tier being represented in a separate project within my solution. I have the web layer (mostly presentation logic), the business layer, and the database layer.

The problem that I run into is that I need to have a reference to and from the middle tier (business logic) tied to each of the other projects. I can add a reference from, for example, the middle tier to the database tier, but when I try to add a reference in the database tier back to the middle tier, Visual Studio barks at me that I am attempting to create a circular reference.

Now I have researched the issue and understand why VS won't let me do this. What I have not found is a fix for this. I'm sure there is a way to allow me to interreference two projects. I know the solution is out there.

Thanks in advance
RS
