Using Entity Framework Code First to connect to an existing database

A Review on Programming Entity Framework Book.

I highly recommend this book. No further knowledge about Entity Framework is required. So you don’t have to know anything about EF1 in order to read and gain benefit of this book.

This series of posts will describe the enhancements I have made to the d...
