ADO.NET 3.5
with LINQ and the Entity Framework
LINQ and the Entity Framework are revolutionizing .NET database Professional
programming. With this book as your guide, you’ll discover how to leverage
these cutting-edge query and object/relational mapping technologies wA
for enterprise-class computing. It provides you with hands-on coding
techniques for data-intensive web and Windows projects. You’ll also get i
t
quickly up to speed on LINQ technologies with the help of C# and VB
h
programming examples. D

Leading Microsoft database authority Roger Jennings first covers LINQ L
Standard Query Operators (SQOs) and domain-specific LINQ to SQL, I
LINQ to DataSet, and LINQ to XML implementations for querying generic N
O
collections. He then delves into the ADO.NET Entity Framework, Entity Data
Q
Model, Entity SQL (eSQL), and LINQ to Entities. Numerous code examples
are integrated throughout the chapters that emulate real-world data
a
sources and show you how to develop C# and VB web site/application or
Windows projects. n.
The information in this book will give you the tools to create and maintain dN
applications that are independent of the underlying relational data.
