Asp.Net MVC Entity Framework Database First Approach Example

We will generally use the entity framework database first approach to create a business model from the existing database. We will learn how to use entity framework database first approach in mvc application with a simple example. To implement this, we will use visual studio 2012 and Entity Framework 5.0.


Let's start with creating a new mvc 4 application for that Open visual studio à Go to File à Select New à Select Project.

Now click on New Connection, a new Dialog will pop up, and you need to configure it. In Server name, you need to add your SQL Server Name and select either Using Windows Authentication or Using SQL Server Authentication to connect SQL Server. Here we selected Using SQL Server Authentication and entered the User name and Password of the SQL server. Last, we will select Database Name: - EmployeeDB. Once we have done, click on the OK button as shown below.

Now let's test how it works.

Adding Controller (Default1Controller)

To add controller, right-click on Controller Folder inside that select Add and then select Controller like as shown below.


Adding new controller in mvc database first application


After clicking on Controller, a new dialog will pop up with the name Add Controller in that mention controller name and select template type and click Add like as shown.

In this Default1Controller, write code to get Employeelist from EmployeeDB database like as shown below.


using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using MVCdatabasefirst.Models;


namespace MVCdatabasefirst.Controllers


public class Default1Controller : Controller


public ActionResult Index()


using (var ctx = new EmployeeDBEntities1())


List<EmployeeDetail> Employeelist = ctx.EmployeeDetails.ToList();

return View(Employeelist);





Now open our database table "EmployeeDetails" and enter some temporary data in it like as shown below.


Inserted user details in database table


Now let Test Database first approach. Here we showed a snapshot in debugging mode.

If we create a view for this controller and bind values, our output will be shown below.
