商品描述
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.
