While this is not online yet, I do have the latest issue of CoDe Magazine in my hands which has (among some other great articles!) an intro article I have written on Entity Framework.

I originally wrote the article using VS2008 Beta1 and Entity Framework beta1, then (as it always seems to happen) the Beta 2 bits of EF were released after the article was finished and with only a few days before the "going to print" deadline. But I was able to rerun all of my tests, through and make sure the content, the code and the screenshots were current, though I wasn't able to add in too much info about the new designer. You'll understand when you see how lengthy the article is.

I also wrote the MVP corner for this issue and finally got a chance to write about something that's been on my mind for a while - and I think it's kinda funny. I was a little surprised they let me write this one!
