![]() ![]() Because we will use this class to represent a particular Movie instance, we should rename the class from Movies to Movie. ![]() In other words, the Wizard gave the class the very same name as the database table. The Wizard created a new data access class named Movies. You can open the Entity Designer at any time by double-clicking the MoviesDBModel.edmx file contained in the Models folder within the Solution Explorer window.įigure 5 – The ADO.NET Entity Data Model Designerįor example, you can use the Entity Designer to change the names of the classes that the Entity Model Data Wizard generates. In the Choose Your Database Objects step, select the Movie database table and click the Finish button (see Figure 4).Īfter you complete these steps, the ADO.NET Entity Data Model Designer (Entity Designer) opens.įigure 1 – Creating a new Entity Data ModelĪfter you create an Entity Data Model, you can modify the model by taking advantage of the Entity Designer (see Figure 5).In the Choose Your Data Connection step, select the MoviesDB.mdf database connection, enter the entities connection settings name MoviesDBEntities, and click the Next button (see Figure 3).In the Choose Model Contents step, choose the Generate from a database option and click the Next button (see Figure 2).Clicking the Add button launches the Data Model Wizard. Select the ADO.NET Entity Data Model template, give the Entity Data Model the name MoviesDBModel.edmx, and click the Add button.In the Add New Item dialog, select the Data category (see Figure 1).Right-click the Models folder in the Solution Explorer window and select the menu option Add, New Item.You can take advantage of the Visual Studio Entity Data Model Wizard to generate an Entity Data Model from a database automatically. In order to use the Entity Framework, you need to create an Entity Data Model. You can enter fake movie data into the grid that appears. Right-click the Movies table and select the menu option Show Table Data. Click the Save button (it has the icon of the floppy) to save the new table with the name Movies.Īfter you create the Movies database table, you should add some sample data to the table.In the Table Designer, add the Id, Title, and Director columns.Expand the MoviesDB.mdf database connection, right-click the Tables folder, and select the menu option Add New Table.Double-click the MoviesDB.mdf file to open the Server Explorer/Database Explorer window.From the Add New Item dialog box, select SQL Server Database, give the database the name MoviesDB.mdf, and click the Add button. ![]() Right-click the App_Data folder in the Solution Explorer window and select the menu option Add, New Item.You can add this table to an ASP.NET MVC project by following these steps: The Movie Database application uses a database table named Movies that contains the following columns: Column Name For example, you can build your MVC Model classes using other O/RM tools such as Microsoft LINQ to SQL, NHibernate, or SubSonic. There are several alternatives to the Entity Framework that you can use with ASP.NET MVC. There is no essential connection between ASP.NET MVC and the Microsoft Entity Framework. ASP MVC MODEL DB TEXT DOWNLOADYou can download Visual Studio 2008 Service Pack 1 or Visual Web Developer with Service Pack 1 from the following address: You need Service Pack 1 in order to use the Entity Framework. This tutorial assumes that you have Visual Studio 2008 or Visual Web Developer 2008 with Service Pack 1. We'll create a Movie Database application that enables you to display and edit movie database records. In order to illustrate how you can use the Microsoft Entity Framework with ASP.NET MVC, we'll build a simple sample application. The Entity Framework enables you to avoid the tedious work of building your data access classes by hand. The Microsoft Entity Framework is an Object Relational Mapping (O/RM) tool that enables you to generate a data access layer from a database automatically. ASP MVC MODEL DB TEXT HOW TOBy the end of this tutorial, you'll understand how to use the Entity Framework to select, insert, update, and delete database records. This tutorial assumes no previous knowledge of the Microsoft Entity Framework. The goal of this tutorial is to explain how you can create data access classes using the Microsoft Entity Framework when building an ASP.NET MVC application. Over the course of this tutorial, we build a web application that illustrates how to select, insert, update, and delete database data by using the Entity Framework. You learn how to use the Entity Wizard to create an ADO.NET Entity Data Model. In this tutorial, you learn how to use ASP.NET MVC with the Microsoft Entity Framework. ![]()
