What is ASP.NET MVC 6?

MVC, Web API, and Web page frameworks are merged into one framework referred to as MVC 6. It is an open-source framework and cross-platform compatible. MVC 6 is supported by mono, Mac, and Linux.

The architecture of MVC 6 :

ASP.NET MVC 6 New Striking Feature

1. Full Framework vs. Cloud-optimized Framework

Removed the dependency of System.Web.Dll from MVC6  because it consumes thousands(i.e. 30,000) of memory per request and response, whereas MVC 6 only requires less amount (i.e. 2000)of memory per request and the response consumes very small memory.

The benefit of the usage of the cloud-optimized framework is that we will encompass a copy of the mono CLR with your internet site. Because of this, we do not need to upgrade the .NET version on the whole machine. A different version of the CLR for a different website runs parallel. The runtime routinely picks the right model of the library while our MVC utility is deployed to the cloud.

The Core CLR is also assumed to be tuned with excessive resource-efficient optimization.

In ASP.NET vNext uses the Roslyn Compiler which automatically compiles the application code. If the user edits a code file and changes added by refreshing the browser without stopping or rebuilding the project.

2. Run-on hosts other than IIS

Using MVC5 we can host it on an IIS server and simultaneously run it on top of an ASP. Net Pipeline.MVC 6 can be self-hosted and uses a flexible pipeline in which we have entire control over the additives that are a part of the pipeline.

3. Environment based configuration system

The configuration system affords surroundings without problems deploying the application on the cloud. Our application works with the configuration providers which retrieves the value from the different configuration sources like XML file. While deploying MVC 5 applications to the cloud requires many configuration changes but because of the environment based configuration system in MVC 6 applications it’s easy to deploy to the cloud

4. Dependency injection

In MVC 6 dependency injection is supported across all of the technologies, WebAPI, MVC, and WebPages.A default dependency injection box is furnished out of the container which affords minimal functionality and is useful while we require the best-limited functionality. By implementing the IServiceProvider interface, it’s easy to add our own dependency injection container. This is the interface that is implemented by the default container as well, so we can replace the default implementation with our own container.

5. Supports OWIN

MVC 6 supports the OWIN abstraction, because of this application consists of a composable pipeline in which we have complete control over the various components in the pipeline.

Important components of an MVC6 application

When we create a new ASP.NET 5 application few files are added to the solution explorer.

The preceding files are new in MVC 6.

1. Config.Json

This file contains the application configuration in various places. There is no need to be concerned about how to connect to various sources to get the confutation value.

In the subsequent code we upload a connection string in the Config.Json file.

"Data": {
"DefaultConnection": {
"ConnectionString": "Server=server_name;Database=database_name;Trusted_Connection=True;MultipleActiveResultSets=true"

2. Project.json

It contains the build information, project dependencies & the commands used by the application.


"webroot": "wwwroot",
"version": "1.0.0-*",
"dependencies": {
"Microsoft.AspNet.Mvc": "6.0.0-beta1",
"Microsoft.AspNet.Server.IIS": "1.0.0-alpha4",
"commands": {
/* Change the port number while self hosting application */
"web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --server.urls http://localhost:5000",

"frameworks": {
"aspnet50": { },
"aspnetcore50": { }

} }

3. Startup.cs

The Application Builder is used as a parameter while the configure technique is used to the Startup magnificence is used by the host.

4. Global.json

It defines the location for the project reference in order that the projects can reference each other.

5. Defining the Request Pipeline

Startup.cs contains a startup method.

public Startup(IHostingEnvironment env) 
// Setup configuration sources.
var Configuration = new Configuration();
Configuration .AddEnvironmentVariables();

6. Create a Controller

Create controller similarly created  in a MVC 5 application.

public class HomeController : Controller 
public IActionResult Index()
return View();

The namespace for MVC6 is Microsoft.ASPNET.MVC in MVC 6 the application does not need to be derived from the controller class. In controllers, there are many default functionalities that mostly need to derive from the controller class. Without accessing all of the functionally provided by the controller class, we can define our controller class. 

public class HomeController: Controller 
public ActionResult Index()
return View();
public string Show()
return "MVC 6 is part of ASP.Net 5";




MVC 6 is a Unified Web Development Framework that is adaptable to Run on other Host than IIS by using different versions of .NET.
