Chapter 2. Your First Entity Framework Application

In this chapter, we will work through the creation of a brand new project that uses Entity Framework. We will create classes that map to tables in the target database. We will then insert a row into that table using the Entity Framework API. We will also query this using LINQ. Next, we will update and delete our test data. Finally, we will take a look at how to handle schema changes.

In this chapter, we will cover the following topics:

  • Creating a new project using Entity Framework

  • Adding the necessary references to be able to write Entity Framework code

  • Creating a new database based on written classes

  • Saving a new record

  • Querying the saved data

  • Deleting and updating the data in the database

  • An introduction to schema changes
