![]() ![]() ![]() If you're new to database design, think of the entity classes as table definitions of a database. The classes you create to define the schema of the data are called entity classes. – The Microsoft SQL Server provider for Entity Framework.EntityFramework.dll – All the common runtime code used by Entity Framework.This NuGet package includes the following runtime assemblies within your project: Entity Framework can be installed, uninstalled, and updated as a NuGet package. Entity Framework and Referencesīy default, Entity Framework is included when you create a new ASP.NET Web Application using the Web Forms template. You will also create an initializer class that you will use to populate the database. Then you will create a context class that manages the entity classes and provides data access to the database. You will begin by creating the entity classes that define the data models for the Web Forms application. Then, you'll let Entity Framework create the database on the fly from these new classes. In this tutorial, you'll create the data models by writing data model classes. ![]() You can map classes to an existing database or use them to generate a database. A class is a construct that enables you to create your own custom types by grouping together variables of other types, methods and events. Code First lets you define your data models using classes. Later in this tutorial series, we'll show you how to use the data to populate navigation and product queries.Įntity Framework supports a development paradigm called Code First. Using Entity Framework allows you to focus on creating the rest of your application, rather than focusing on the data access fundamentals. LINQ provides patterns for querying and updating data. Using Entity Framework, you can issue queries using LINQ, then retrieve and manipulate data as strongly typed objects. It lets you work with relational data as objects, eliminating most of the data-access code that you'd usually need to write. These are the features introduced in the tutorial:Įntity Framework is an object-relational mapping (ORM) framework. How to update and configure the application to support the database.How to initialize and seed the database.When you've completed this tutorial, you will have built a group of data-access classes that are in the Models folder of the project. This tutorial builds on the previous tutorial "Create the Project" and is part of the Wingtip Toy Store tutorial series. This tutorial describes how to create, access, and review data from a database using ASP.NET Web Forms and Entity Framework Code First. A Visual Studio 2013 project with C# source code is available to accompany this tutorial series. This tutorial series will teach you the basics of building an ASP.NET Web Forms application using ASP.NET 4.5 and Microsoft Visual Studio Express 2013 for Web. ![]()
