Circular Reference Hell!

Hi, I am trying to use a class in multiple projects. It is a simple class containing properties of a given database table. The class, DbTable, is defined in my main DbCompare project. I also want to use this class in a Control Library (UserControl) project which will itself be used in the DbCompare project. However, I am in circular reference hell! When I build the DbCompare project, I get the warning 'DbCompare.DbTable' is defined in multiple places; using definition from 'D:\Proj_net\DbCompare\DbTable.cs'. Does anyone know how to do this? TIA, Royce
