Interesting LINQ article

Hi all,

Just came across this little article on the codeproject that really is short and sweet at describing LINQ (not L2S) in a 3 tier scenario.

Worth a peek...

enjoy!!

This is really nothing more than LINQ to SQL, except he's creating the entities by hand instead of using the designer. Nothing wrong with that if you don't mind all the extra work.

hi lee - thanks for the 'nod' on the book thread

i think my *interest* here was the fact that you could template build the entities *by hand* and get all the linqie goodness without having all the contraints that the designer places on the BDAL (linq bll/dal).

but as you say, it's just hand rolled l2s - but quite simple and certainly gave me an insight into how you could use a very lightweight linq dal merely by adding some *decoration* to the DAL entities.

further thoughts welcome...

Offhand, I can't think of any serious restrictions placed by the designer, other than the datacontext and entities being munged into the same physical file, though in practice that shouldn't make any real difference.

You'll also be lacking the ability to respond to events that the designer automatically creates, though I can't think of many cases where I've done this anyway.

Decorating the entities by hand does allow you to implement only the functionality you need, which for a template-based scenario might be a good thing.
