Programming Entity Framework: DbContext By Julia Lerman and Rowan Miller
In addition to Code First, EF 4.1 introduces simpler
EF coding patterns with the DbContext, DbSet, ChangeTracker and
Validation APIs. This second mini-book will take the reader on a tour
of these new features and how to take advantage of them. These new
classes and APIs let the user focus on the most common coding tasks with
Entity Framework and streamlines access to patterns which are
frequently used, but were previously non-intuitive and complicated to
code. The Validation API that comes with DbContext leverages the
existing .NET 4 IValidatableObject and ValidationAttributes as well as
providing additional validation features. You will learn the ins and
outs of getting the most from server side validation from the DbContext.
