An asp net mvc application is built with net framework version 4 5 I want to r

ASP.NET is a popular programming language used for building web applications. It is a part of the .NET framework and provides developers with a powerful and platform to dynamic and interactive websites. In this article, we will explore the features of ASP.NET and provide examples to help you understand its usage.

ASP.NET is built on top of the .NET framework, which means it inherits all the benefits and functionalities of the framework. It allows developers to write code in multiple languages, such as C#, VB.NET, and F#, making it a versatile choice for developers with different language preferences.

One of the key features of ASP.NET is its Model-View-Controller (MVC) architecture. This architectural pattern separates the application into three main components: the model, the view, and the controller. The model represents the data and business logic, the view is responsible for rendering the user , and the controller handles the user input and coordinates the interaction between the model and the view.

To illustrate the usage of ASP.NET, let's consider an of building a simple ASP.NET MVC application. We will assume that the application is built with .NET Framework version 4.5.

First, let's create a new ASP.NET MVC project in Visual Studio. Open Visual Studio and select “New Project” from the File menu. In the New Project dialog, choose “ASP.NET Web Application” and give your project a name. Select the MVC template and click “OK” to create the project.

Once the project is created, you will see a folder structure that includes various for , views, and models. The controllers folder contains the controllers that handle the user and coordinate the interaction between the model and the view. The views folder contains the HTML templates that define the user interface, and the models folder contains the classes that represent the data and business logic.

Let's create a simple controller that handles a user request and returns a view. In the controllers folder, add a new class file and name it “HomeController.cs”. Open the file and add the following code:


using System.Web.Mvc;

namespace YourNamespace.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
    }
}

In this code, we define a controller class named “HomeController” that inherits from the “Controller” base class provided by ASP.NET MVC. The “Index” method is the default action method that will be called when a user requests the home page. It simply returns a view.

Now, let's create a view that will be rendered when the user requests the home page. In the views folder, add a new folder named “Home” and inside that folder, add a new view file named “Index.cshtml”. Open the file and add the following code:


@{
    ViewBag.Title = "Home Page";
}

Welcome to our ASP.NET MVC Application!

This is a simple example of an ASP.NET MVC application built with .NET Framework version 4.5.

In this code, we define the title of the page using the ViewBag object and then add a heading and a paragraph to the view.

Now, when you run the application, you should see the home page with the heading and paragraph we defined in the view.

ASP.NET provides many other features and functionalities that can be used to complex and robust web applications. It supports data access various technologies like Entity Framework and provides built-in authentication and authorization mechanisms. It also supports client-side scripting using JavaScript and integrates well with popular front-end frameworks like Angular and .

In conclusion, ASP.NET is a powerful programming language for building web applications. Its MVC architecture, support for multiple languages, and integration with the .NET framework make it a versatile choice for developers. By following the examples provided in this article, you can start building your own ASP.NET MVC applications and explore the vast capabilities of this programming language.
