In this chapter, I have introduced you to LINQ to SQL and some of its most basic terminology, such as DataContext objects, entity classes, associations, and concurrency conflict detection and resolution.
I also showed you how to generate your entity classes and external mapping file for the extended Northwind database. These entity classes will be used extensively throughout the LINQ to SQL examples.
Last, I provided a couple of common methods that many of the examples in the subsequent LINQ to SQL chapters will rely on.
The next step is to arm you with some tips and show you how to use the necessary tools to leverage LINQ to SQL, and this is exactly what the next chapter is about.
