Linq in layered architecture...

Question

I have been using layered architecture since last 2 Years. that contains.

1. Presentation(asp.net)
2. Business
3. Data Layer
4. Entity Objects(while we may/may not merge entity objects layer with DL)

Now, I am thinking to use Linq. never used this before. I wonder where to place it. with couple of questions.

1. I don't want to write inline sql, I prefer to use storedprocedures. Linq support that??
2. If I will replace Data Layer with Linq.will this disturb any other layer??
3. Any sample available with layered architecture+LINQ. Offcourse there are alot of LINQ sample available but a starterkit application with layered architecture+Linq??

I hope, your replies will increase my knowledge about LINQ and layered architecture with LINQ.

Regards,
Azam.

Azam: 1. LINQ supports the use of stored procedures. 2. It depends on the code in the data access layer; I have replaced subsonic with LINQ but the code supported doing that. 3. As for the last; I have not seen any great ones. You might want to pay close attention to how LINQ to SQL supports updates of disconnected data before going any further.
