Should you use a partial class across projects?

Question

I have a class library with all my database logic. My DAL/BLL.

I have a few web projects which will use the same database and classes, so I thought it was a good

While I agree with you Neil when it comes to pre-linq development, I also wish I could be able to do this in order to split up bussiness logic from partial classes generated by Linq2SQL designer. For example:

Northind.DAL (prj)
-NorthindDataContext (EntityNamespace set to "Northwind.BLL")
--Product() (Entity, partial class auto-generated)
--Category() (Entity, partial class auto-generated)
--Supplier() (Entity, partial class auto-generated)

Northind.BLL (prj)
-Product() : IMyCustomEnityInterface, BaseEntity (override OnValidate(), etc)
-Category() : IMyCustomEnityInterface, BaseEntity (override OnValidate(), etc)
-Supplier() : IMyCustomEnityInterface, BaseEntity (override OnValidate(), etc)

Unfortunately, we can not do this... actually I'd love to know what the recommended way of splitting up layers/tiers when using LINQ.
