Looking for LINQ to SQL N-Tier example

I'm looking for an example / guidelines for leveraging LINQ to SQL in an
N-Tier environment. Specifically I'm looking for an example where there is a
presentation layer, an application layer, and a database. There are plenty
of examples showing how to create LINQ objects and then connect them as
datasources directly to web controls that consume datasources. I"m looking
for a way to create the LINQ objects on the application server and then
propagate them to the web server to have them consumed as datasources there.

Any help is appreciated,
Thanks.

If you've already got your linq objects, with all their properties set,
then you just need to return these objects to the client (using Remoting
or WCF or whatever). So you just take the linq examples you already have
an use them in the application server in the methods that are used to
fetch/update/insert/delete the persistent instances of these objects in
the underlying datasource (MSSQL Server).... what goes on between the
client and server has nothing to do with linq though, so the fact that
you're programming n-tier really doesn't matter.

Hello groknroll,

I recommend you to look at any 3 tier application sample, like there http://www.15seconds.com/issue/011023.htm

and start thinking about the LINQ from "data layer" like LINQ to SQL - it's
simplies way to get tuned to LINQ

after that u will understand where and how apply LINQ to other collections
