Getting Started with Entity Framework 6 Database First using MVC 5

By Tom FitzMacken|

Using MVC, Entity Framework, and ASP.NET Scaffolding, you can create a web application that provides an interface to an existing database. This tutorial series shows you how to automatically generate code that enables users to display, edit, create, and delete data that resides in a database table. The generated code corresponds to the columns in the database table.

This part of the series focuses on creating a database and populating it with data.

This series was written with contributions from Tom Dykstra and Rick Anderson. It was improved based on feedback from users in the comments section.


This topic shows how to start with an existing database and quickly create a web application that enables users to interact with the data. It uses the Entity Framework 6 and MVC 5 to build the web application. The ASP.NET Scaffolding feature enables you to automatically generate code for displaying, updating, creating and deleting data.

This topic addresses the situation where you have a database and want to generate code for a web application based on the fields of that database. This approach is called Database First development. If you do not already have an existing database, you can instead use an approach called Code First development which involves defining data classes and generating the database from the class properties.

For an introductory example of Code First development, see Getting Started with ASP.NET MVC 5. For a more advanced example, see Creating an Entity Framework Data Model for an ASP.NET MVC 4 App.

For guidance on selecting which Entity Framework approach to use, see Entity Framework Development Approaches.


Visual Studio 2013 or Visual Studio Express 2013 for Web

Set up the database

To mimic the environment of having an existing database, you will first create a database with some pre-filled data, and then create your web application that connects to the database.

This tutorial was developed using LocalDB with either Visual Studio 2013 or Visual Studio Express 2013 for Web. You can use an existing database server instead of LocalDB, but depending on your version of Visual Studio and your type of database, all of the data tools in Visual Studio might not be supported. If the tools are not available for your database, you may need to perform some of the database-specific steps within the management suite for your database.

If you have a problem with the database tools in your version of Visual Studio, make sure you have installed the latest version of the database tools. For information about updating or installing the database tools, see Microsoft SQL Server Data Tools.

Launch Visual Studio and open the Server Explorer pane. To add a new database, right-click Data Connections and select Add Connection.

add new connection

If this is the first data connection you have added, you will be prompted to choose a Data source. Select Microsoft SQL Server. If you have added a data connection in the past, you might not see this dialog window.

choose data source

If you have a server that you prefer to use, you can specify the name of that server; otherwise, use the local database that comes with Visual Studio by specifying (localdb)\v11.0 for the server name. Name the database ContosoUniversity.

create database

Click OK. When prompted to create a new database, select Yes.

Your new database appears under the Data Connections node. The database name may be prefixed with some additional identifiers. Right-click the database, and select New Query.

new query

In the query window, you will add T-SQL commands to create 3 tables (Course, Student, and Enrollment), and add some example data to those tables. Add the following code to the query window:

CREATE TABLE [dbo].[Course] (
    [CourseID] INT           IDENTITY (1, 1) NOT NULL,
    [Title]    NVARCHAR (50) NULL,
    [Credits]  INT           NULL,

CREATE TABLE [dbo].[Student] (
    [StudentID]      INT           IDENTITY (1, 1) NOT NULL,
    [LastName]       NVARCHAR (50) NULL,
    [FirstName]      NVARCHAR (50) NULL,
    [EnrollmentDate] DATETIME      NULL,

CREATE TABLE [dbo].[Enrollment] (
    [EnrollmentID] INT IDENTITY (1, 1) NOT NULL,
    [Grade]        DECIMAL(3, 2) NULL,
    [CourseID]     INT NOT NULL,
    [StudentID]    INT NOT NULL,
    CONSTRAINT [FK_dbo.Enrollment_dbo.Course_CourseID] FOREIGN KEY ([CourseID]) 
        REFERENCES [dbo].[Course] ([CourseID]) ON DELETE CASCADE,
    CONSTRAINT [FK_dbo.Enrollment_dbo.Student_StudentID] FOREIGN KEY ([StudentID]) 
        REFERENCES [dbo].[Student] ([StudentID]) ON DELETE CASCADE

(Title, Credits) 
Values ('Economics', 3), ('Literature', 3), ('Chemistry', 4);

(LastName, FirstName, EnrollmentDate)
('Tibbetts', 'Donnie', '2013-09-01'), 
('Guzman', 'Liza', '2012-01-13'), 
('Catlett', 'Phil', '2011-09-03');

INSERT INTO Enrollment
(Grade, CourseID, StudentID)
(2.00, 1, 1),
(3.50, 1, 2),
(4.00, 2, 3),
(1.80, 2, 1),
(3.20, 3, 1),
(4.00, 3, 2);

Execute the query (Ctrl + Shift + E). The tables now exist in the database.

show new tables

After executing the query, you can close the query window without saving the file.

To see that the tables are populated with data, right-click a table, and select Show Table Data.

show table data

An editable view of the table data is displayed.

show table data results

Your database is now set up and populated with data. In the next tutorial, you will create a web application for the database.
