As I understand it, when you implement IQueryable, you've tied all your client code to *that specific implementation*. Whereas with the entities framework, you can simply swap out the entity provider for a different one. It's basically one level higher than IQueryable. That means you can write your code against Firebird (or whatever), and later swap in another ADO.NET data provider without too much trouble. You can even do it dynamically at runtime. Additionally, it allows the IDE to generate all kinds of graphical representations of your data source (which are mapped to "entities") so you build up your business data object via a graphical UI, and then use them in your code. Personally, I've never been a fan of this kind of programming... but that's just me :-) Dean. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
