LINQ to SQL in the business world

[mal]

Hi,

A screencast on Linq to SQL in the business world would be a good
idea. The examples that are on most blogs are basic search using one
or more fields and throw the results in a grid. But what about real
world apps where you have multiple controls to search from.

Also the seperation of business objects and Linq entities. To me Linq
entities are your business objects now because for most of us, they
reflect the data in a table, so are business objects dead? That is a
good discussion.

Also it would be good to discuss some of the limitations with Linq to
SQL. How to update the designer when the database changes. How well
does it scale. Differences with Linq and the Entity Framework.

Hope there are some good topics to cover. I'd love to do a screen
cast or tutorial or help if I can.

Regards
Malcolm
