The ADO.NET Entity Framework 4.1 was released in April. There are a lot of interesting features. However the most fantastic one, I suppose, is a Code First development.
In my previous application we had to use a nHibernate because we were needed to create a database dynamically when the application is running. So when Microsoft announced a Code First feature I spent lots of time on this.
And today I discovered a really good article in the new May’s MSDN magazine.
I hope this is a nice place to start with understanding of Code First.
