Introduction

The MVC in 'ASP.NET stands for Model View Controller, which is not a programming language but a design pattern used to develop the application. The application created using the MVC design pattern will get divided into 3 Components. So, which model will contain all the data retrieved on the user's request? The view will have UI code, and the Controller will include Business logic code. 

ASP.NET MVC Architecture and Lifecycle

The properties of MVC are:

  • Effective look
  • Loose Coupling
  • Lightweight code
  • Testing is Very Easy
  • Rapid application integrated development

     

ASP.NET MVC Architecture

ASP.NET MVC splits an application into three components: Model, View, and Controller.

  1. Model: The model depicts the shape of the data. We use a C# class to define a model. Model objects store data recovered from the database.
  2. View: The view is the user interface. View show model data to the user and enable them to modify them. ASP.NET MVC view is HTML, CSS, and some special Razor syntax that makes it easier to communicate with the model and controller.
  3. Controller: The controller component handles the user request. Generally, the user uses the view and raises an HTTP request, which the controller will take. The controller processes the request from view and returns the suitable view as a response.

We can better understand ASP.NET MVC architecture with the following car example:

1. User interface (View):

                @source - freepik.com

2. Mechanism (Controller):

                @source - vecteezy.com

3. Storage (Model):

                 @source - freepik.com

The following figure shows the interaction between Model, View, & Controller:

Architecture of MVC

MVC Architecture

The user will request the page that the user would like to retrieve. The requested page will go to the controller. On the controller Route, the controller will check config. The requested page will get transferred to the Model from Controller. On the model, there will be two steps,

Page initialization will get started & Then the result set will be generated.

After these operations, result sets will get unloaded to view through the view engine.

ASP.NET MVC Lifecycle

We can see the life Cycle of ASP.NET MVC in the following figure:

Life Cycle of MVC

The ASP.NET MVC lifecycle begins with the application startup, where routes are registered. A user's request is processed by the Routing module, which maps the request to a controller action. The Controller handles the request, executing the specified action method. The action method processes the request, often interacting with the Model for data. It then returns a ViewResult, which is passed to the View Engine to render the view. The view is generated using the corresponding View Template, which combines HTML with dynamic content. Finally, the response is sent back to the client's browser. This structured flow ensures a clear separation of concerns.

Frequently Asked Questions

What is the life cycle in MVC?

The MVC lifecycle includes request routing, controller action execution, interaction with models for data, and rendering views via the view engine, finally sending the response back to the client, ensuring a structured request-response flow.

Why is MVC used?

MVC (Model-View-Controller) is used for its clear separation of concerns, improving code maintainability, testability, and scalability. It allows independent development and testing of the UI, business logic, and data layers, enhancing overall application architecture.

What is MVC real life example?

A real-life example of MVC is an online shopping platform: the Model manages product data, the View displays product listings and user interfaces, and the Controller handles user interactions like adding items to the cart and checkout processes.

Are ASP.NET and MVC the same?

ASP.NET is a web platform. It delivers a layer on top of IIS (the webserver), facilitating web applications & services. ASP.NET MVC is a framework especially for building web applications. It sits on top of ASP.NET and uses APIs provided by ASP.NET.
