Code-First Development with Entity Framework

By: Sergey Barskiy

Overview of this book

<p>Entity Framework Code-First enables developers to read and write data in a relational database system using C# or VB.NET. It is Microsoft's answer to demand for an ORM from .NET developers.</p> <p>This book will help you acquire the necessary skills to program your applications using Entity Framework. You will start with database configuration and learn how to write classes that define the database structure. You will see how LINQ can be used with Entity Framework to give you access to stored data. You will then learn how to use Entity Framework to persist information in a Relational Database Management System. You will also see how you can benefit from writing ORM-based .NET code. Finally, you will learn how Entity Framework can help you to solve database deployment problems using migrations.</p>

Summary

In this chapter, we took a look at how data is stored in RDBMS systems. We saw the shortcomings of using embedded SQL to access the data. We understood what ORM tools are all about and what problems they solve. We examined the history behind Entity Framework. We saw the capabilities of Entity Framework. Finally, we had a brief excursion into the Entity Framework architecture.

In the next chapter, we will actually build our first application based on Entity Framework Code-First.
