It has been three years and I’m still trying to get the word ‘‘grok’’ into everyone’s mainstream vocabulary (see the introductions to my last two books), and one of the things that I am ‘‘grokking’’ is the new LINQ technology coming out of the Microsoft campus.

CHAPTER 4 ■■■ Querying the EDM You have spent the previous two chapters creating and exploring an Entity Data Model. Chapter 2 discussed the different ways an EDM can be created, and Chapter 3 explored the many facets of the EDM both internally and externally. It is now finally time to write some code. This chapter will discuss how to write queries against the EDM by using the LINQ-to-Entities syntax and the Entity SQL syntax, both provided by the Entity Framework. This chapter will also discuss the difference between query syntax and method syntax and when you might use one over the...

In this tutorial, you learn how to build model classes and perform database access by taking advantage of Microsoft LINQ to SQL In this tutorial, we build a basic Movie database application. We start by creating the Movie database application in the fastest and easiest way possible. We perform all of our data access directly from our controller actions. Next, you learn how to use the Repository pattern. Using the Repository pattern requires a little more work. However, the advantage of adopting this pattern is that it enables you to build applications that are adaptable to change and can...
