ASP.NET MVC is a web application framework developed by Microsoft, which implements the Model-View-Controller (MVC) architectural pattern. It is a powerful framework for building dynamic, data-driven web applications. The MVC pattern separates an application into three main components:

• Model: Represents the application's data and business logic. It is responsible for retrieving data from the database and performing operations on it.
• View: Represents the user interface of the application. It displays the data provided by the model to the user and sends user commands to the controller.
• Controller: Acts as an intermediary between the Model and the View. It processes user input, interacts with the model, and selects the appropriate view to render the response.

Key Features of ASP.NET MVC

• Separation of concerns: The MVC pattern promotes a clean separation of concerns, making the application easier to manage and test.
• Testability: ASP.NET MVC is designed to support unit testing, allowing developers to test their applications more effectively.
• Full control over HTML: Developers have complete control over the generated HTML, which is beneficial for creating responsive and SEO-friendly web applications.
• Routing: ASP.NET MVC uses a powerful routing engine that allows developers to define URL patterns and map them to specific controllers and actions.

Sample Code

Below is a simple example of an ASP.NET MVC application:

1. Model

        
        public class Product
        {
            public int Id { get; set; }
            public string Name { get; set; }
            public decimal Price { get; set; }
        }
            

2. Controller

        
        using System.Collections.Generic;
        using System.Web.Mvc;

        public class ProductController : Controller
        {
            public ActionResult Index()
            {
                var products = new List<Product>
                {
                    new Product { Id = 1, Name = "Product 1", Price = 10.00M },
                    new Product { Id = 2, Name = "Product 2", Price = 20.00M },
                    new Product { Id = 3, Name = "Product 3", Price = 30.00M }
                };
                return View(products);
            }
        }
            

3. View

        
        @model IEnumerable<Product>

        <h2>Product List</h2>
        <table>
            <thead>
                <tr>
                    <th>Id</th>
                    <th>Name</th>
                    <th>Price</th>
                </tr>
            </thead>
            <tbody>
                @foreach (var product in Model)
                {
                    <tr>
                        <td>@product.Id</td>
                        <td>@product.Name</td>
                        <td>@product.Price</td>
                    </tr>
                }
            </tbody>
        </table>
            

Conclusion

ASP.NET MVC is a robust framework that provides developers with the tools to build scalable and maintainable web applications. By following the MVC pattern, developers can create applications that are easier to test, manage, and extend.
