Hi,

While using 3 layer/tier approach with LINQ, the suggestion would be to use LINQ data model in Data access layer. and write the LINQ To SQL methods in DAL.

From BLL make the call to get the data from DAL and pass it on to the UI Layer.

The twist remains, if you want to expose your BLL by using any service. Then you have to write an Translator service which converts business entities into Data Contracts and vice versa.

I Hope this helps!.
