Had a system with v2 running well. Swapped out the Visual Studio reference for the v2 DLL to the v3 DLL. Rebuilt the project. Errors.

I am using SQL Server 2005 on the back-end and am implementing ActiveRecord.

    v3.x isn’t entirely backward compatible with v2.x. The collection classes aren’t really needed any more. v3.x uses List instead of *Collection (the old v2 *Collection classes derived from this already).
