First MVC 6 and EF 7 Application (with Empty Project Template)

Part 1

If you are one of that techie who is tracking the progress of ASP.NET 5, you probably know that RC 1 of ASP.NET 5 is available now. This article explains how a simple MVC 6 application could be developed from ground up by using an Empty Project Template. This article is based on the following software:

  • Visual Studio 2015

  • ASP.NET 5 RC 1

  • Entity Framework 7 RC 1

Before you start you need to ensure that you have installed them correctly before you proceed further.

Let’s start here!

Open VS 2015 and select File—–New—-Project menu option. In the New Project dialog choose ASP.NET Web Application, give some project name and click OK button.

In the project template dialog, select Empty under ASP.NET 5 Preview Templates section.

Next, open Project.json file in the VS editor. The Project.json file is a JSON file and contains the entire project configuration like project dependencies, target frameworks and much more. For this example, you have to add some NuGet packages required to develop and run the application. You can enhance project dependencies in two ways:

  • Right click on the References node and choose Manage NuGet Packages. This is very similar to MVC 5.x projects. Once added the NuGet package entries are automatically added to the Project.json file.

  • Add NuGet package dependencies in the Project.json file.

Let’s make use of the later approach.

We won’t go into every minute details of each and every package in this article. It is sufficient to mention that:

  • Microsoft.AspNet.Mvc is the core MVC 6 package

  • Microsoft.AspNet.Mvc.TagHelpers contains tag helpers (discussed later)

  • EntityFramework.MicrosoftSqlServer provides Entity Framework 7 support

Then, right click on the project and choose Add > New Item to open the Add New Item dialog.

Select ASP.NET Configuration File from the list, name it AppSettings.json and click on Add to add the file to project root folder.

The AppSettings.json file has the entire application specific configuration. There is a difference between Project.json and AppSettings.json. The former stores project configuration that is necessary to compile and run the project. The later stores application configuration utilized in the code.

Next you have to add four folders under the project root namely Models, Views, Controllers and Classes. The purpose of the first three is quite obvious. The Classes folder will store other classes required in the application such as a DbContext class. You can give any other name to this folder.

Then add a class called AppSettings in the Classes folder and write the following code:

public class AppSettings


public static string ConnectionString { get; set; }


The AppSettings class has a single static property – ConnectionString – that intends to hold the database

connection string. This property is taken from the Startup class as discussed recently. Once assigned you can reach out the database connection string from anywhere in the application.

Now open Startup.cs file. The code from the Startup class is implored whenever the application runs. You will find that the Startup class has two methods – ConfigureServices() and Configure(). Both of them have special meaning to the framework and hence their name must remain unchanged.

Edit the Startup file to include a few namespaces and a public constructor.

using Microsoft.AspNet.Hosting;

using Microsoft.Dnx.Runtime;

using Microsoft.Extensions.Configuration;

using Microsoft.Extensions.PlatformAbstractions;

using Microsoft.Data.Entity;

using MVC6Demo.Classes;

namespace WebApplication1


public class Startup


public Startup(IHostingEnvironment env,

IApplicationEnvironment app)



public void ConfigureServices(IServiceCollection services)



public void Configure(IApplicationBuilder app)





Take note of the namespaces at the top. They are needed by the code that you will fill in these methods sooner. Also take note that the constructor accepts two parameters: IHostingEnvironment and IApplicationEnvironment. These 3 methods are executed by the framework in the same order – Startup(), ConfigureServices() and Configure().

Next, add the following code to the Startup() constructor.

public Startup(IHostingEnvironment env,

IApplicationEnvironment app)


ConfigurationBuilder builder = new ConfigurationBuilder();



IConfigurationRoot config = builder.Build();

AppSettings.ConnectionString = config.Get<string>



The Startup constructor mainly reads the AppSettings.json file and stores the database connection string into the AppSettings class. The ConfigurationBuilder class is responsible for reading and loading the configuration information. The SetBasePath() method sets the base path where the configuration file(s) is located. The ApplicationBasePath means the physical path of the project’s root folder.

The AddJsonFile() adds AppSettings.json file to the list of configuration files to be processed. You can have multiple configuration files per project. The Build() method reads the configuration and returns it as an instance of IConfigurationRoot.

To read it, you can use Get<T>() method on the IConfigurationRoot object. Now the database connection string could be accessed from anywhere in the application in typed manner.

Then modify the ConfigureServices() method as shown below:

public void ConfigureServices(IServiceCollection services)





The ConfigureServices() method specifies the features that are available to your application. In this case your application is made available the services of the MVC framework and the Entity Framework.

Now modify the Configure() method as shown below:

public void Configure(IApplicationBuilder app)



app.UseMvc(routes =>



name: “default”,

template: “{controller=Home}/{action=Index}/{id?}”);



The Configure() method tells the framework that you want to use static files feature and MVC features. The static files feature allows you to access static files such as .htm and .html. If you don’t specify this feature and attempt to access the static files you will get an error. Of course, if you don’t need this feature you can skip this line.

The UseMvc() call is important because it not only tells the framework that your application is using MVC but also configures the routing system.

Ok. Now add HomeController to the Controllers folder using the Add New Item dialog. The default HomeController looks like this:

public class HomeController : Controller


public IActionResult Index()


ViewBag.Message = “Hello from MVC 6!”;

return View();



Notice that the Index() action returns IActionResult. The Index() action is quite straightforward and simply sets Message property on the ViewBag.

Then add Home subfolder under Views folder. Right click on the Home folder and open the Add New Item dialog again to add Index view to the project.

Add the following HTML markup to the Index view.



<title>My First MVC 6 Application</title>






The Index view simply outputs the Message ViewBag property on the response stream.

Run the application by pressing F5.

We conclude for now. Keep coding!!
