Another project structure question:

I have a Common project which contains my custom classes and collections.

I have a Biz project which contains by business helper classes. The Biz project contains a reference to the Common project.

I have Order and OrderCollection classes in my Common project which will contain order data. I have another Dealer class that I want to lazy load into my Order class and expose as a property. I will be loading this dealer through my Biz project.

I can't add a reference to my Biz project to my Common project because it will create a circular reference. How are other people doing this? In the application I inherited the container classes exist in the Biz layer, and I don't want to do this.

Thanks!!!
