Larry, this is a tough one to answer. You are right that the academic views dont do so well in the real world in many areas. Entity Framework has not been used so much yet in commercial environments from what I can see with many people waiting for the features we see in this upcoming version.

Even then though, I would be deciding on a case by case basis when and how to implement it, rather than adopting a blanket approach.

I have done a model first with some complex types. The SQL script implements all these as column in the same db table. I was expecting different tables. What real advantage is this? It certainly doesn’t look like normalized database tables. In my case there are cases where regular old LINQ to SQL works very well (such as transaction processing) while more complex stuff like customer and client management benefit from entity models.
Where do you draw the lines? The academic views really don’t do well in the real world.
In our practical world we have business logic out on the edge and at other levels as the data is crunched, filterd, parsed, and spread around.
Just looking for advice before we start this next round of development/enhancement.

How to execute the generated script/DLL against my database, if I’m using MDF or SDF?

Haven’t been able to figure it our, despite intensive search.

Looks like this will be possible. Just do a Google to find out more as there are plenty of detailed posts on the matter, such as this one discussing POCO in Entity Framework 4.

Wow, looks like Entity Framework 2.0 will be finally useful.
Will it be possible to create POCO using model designer? POCO will be supported, but will we be able to edit them using the designer.
What about lazy loading and performance comparing to pure ADO.NET objects?
