What is MVC?

by

MVC is a framework used to create web applications. The web application base builds on Model-View-Controller pattern which separates the application logic from UI, and the input and events from the user will be controlled by the Controller.

For an ASP.NET interview question regarding MVC (Model-View-Controller), the correct answer would typically entail an explanation of the MVC architectural pattern used in ASP.NET development. Here’s a concise answer:

“MVC, or Model-View-Controller, is a software architectural pattern used in ASP.NET development for creating web applications. It separates an application into three main components:

  1. Model: Represents the data and the business logic of the application. It manages the data, logic, and rules of the application domain. In ASP.NET, models are often implemented as classes that interact with a database or other data sources.
  2. View: Represents the user interface of the application. It displays the data to the user and captures user input. Views in ASP.NET are typically implemented using HTML, CSS, and Razor syntax, and they render the data provided by the controller.
  3. Controller: Acts as an intermediary between the Model and the View. It receives user input, processes it (such as querying the model for data or updating the model), and determines which view to render in response. Controllers in ASP.NET handle incoming HTTP requests, execute the appropriate actions, and return the corresponding views.

Using the MVC pattern promotes a separation of concerns, making it easier to manage and maintain large-scale applications. It also allows for better testability, as each component can be tested independently.”

This answer provides a clear overview of what MVC is and how it’s used within the context of ASP.NET development. Additionally, it highlights the benefits of using MVC in web application development.
