Mastering Entity Framework

By: Rahul Rajat Singh

Overview of this book

<p>Data access is an integral part of any software application. Entity Framework provides a model-based system that makes data access effortless for developers by freeing you from writing similar data access code for all of your domain models.</p> <p>Mastering Entity Framework provides you with a range of options when developing a data-oriented application. You’ll get started by managing the database relationships as Entity relationships and perform domain modeling using Entity Framework. You will then explore how you can reuse data access layer code such as stored procedures and table-valued functions, and perform various typical activities such as validations and error handling. You’ll learn how to retrieve data by querying the Entity Data Model and understand how to use LINQ to Entities and Entity SQL to query the Entity Data Model.</p>

Chapter 10. Managing Concurrency Using Entity Framework

So far, we have seen how we can use the various approaches of Entity Framework, domain modeling, performing model validations, managing Entity relationships, querying data using LINQ to Entities, and Entity SQL. When we talk about data-driven applications, concurrency and transaction management also plays crucial role. In this chapter, we will take a look at the various concurrency management techniques using Entity Framework. In the next chapter, we will see how to manage transactions with Entity Framework.
