Zeeshan Hirani christmas present
Zeeshan is a great EF community contributor with his blog and, since a short time ago, he also answers a lot in msdn forum.
I take advantage of this post to tell you that the msdn forum url will change this week.
Zeeshan makes us a very usefull christmas present with a big article about EF (514 pages !!!) and also the code of the article.
