In this chapter, we will see how we can perform model validations using Entity Framework. We will take a look at the various approaches available for model validations, and implement a small sample application to validate the models using each approach. Finally, we will take a look at which approach should be used in which scenario. Model validations discussed in this chapter are not specific to the Database First approach. It is a functionality related to entities so it is applicable to all three approaches of Entity Framework.

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>
