Chapter 14: LINQ to DataSet
The heart of the chapter tackled querying DataSets, and you learned how LINQ to DataSet also supports
data binding using DataSets. Finally, you saw how LINQ to DataSet supports the LINQ set operators
to effectively compare source elements within a DataSet, whether they are in the same table or multiple
tables within the DataSet.
So far, you??™ve done everything in this book manually, such as create LINQ to SQL entity classes. The next
chapter discusses several tools that make working with LINQ even simpler.

Advanced LINQ
to SQL Topics
Visual Studio 2008 provides several tools to help facilitate the creation of entity classes and their
mapping to relational objects in a database. These tools also help define the entity associations
(database relationships) that the entity classes will use when working with two or more tables.
In essence, these tools help create an object model. The object model is defined within an application
that will then be mapped to database objects. It is a fully functional object model, one that supports
a mapping to stored procedures and user-defined functions as well as DataContext methods for
data transport.
