1. Introduction

Asp.Net is a web application framework developed by Microsoft. It is a powerful and flexible platform that allows developers to build web applications using a wide range of programming languages, including C#, F#, and Visual Basic. Asp.Net provides a number of features that make it an ideal choice for building web applications, such as built-in security, performance optimization, and easy deployment.

2. Prerequisites

Before we get started with building our Asp.Net application, we need to make sure that we have the following prerequisites installed on our system:

• Visual Studio 2019 or later version
• .Net SDK
• SQL Server Express
• Web browser

3. Setting up the development environment

Once we have installed the prerequisites, we can set up our development environment. To do this, we need to follow these steps:

1. Open Visual Studio and select "Create a new project."
2. Choose "ASP.NET Web Application" from the list of project templates and click "Next."
3. Choose "Web Application" as the project type and click "Create."

4. Creating a new Asp.Net project

Once we have set up our development environment, we can create a new Asp.Net project. To do this, we need to follow these steps:

1. In Visual Studio, select "Create a new project."
2. Choose "ASP.NET Web Application" from the list of project templates and click "Next."
3. Choose "Web Application" as the project type and click "Create."

5. Adding a database

Most web applications require a database to store data. In Asp.Net, we can easily add a database to our application using Entity Framework. To add a database, we need to follow these steps:

1. In Visual Studio, right-click on the project and select "Add -> New Item."
2. Choose "Data" from the list of project templates and select "ADO.NET Entity Data Model" from the list of items.
3. Choose "EF Designer from database" and click "Next."
4. Enter the connection string for the database and click "Next."
5. Select the tables that you want to use in your application and click "Finish."

6. Creating a model

Once we have added a database to our application, we need to create a model. A model is a representation of the data in the database. To create a model, we need to follow these steps:

1. In Visual Studio, right-click on the project and select "Add -> New Item."
2. Choose "Data" from the list of project templates and select "ADO.NET Entity Data Model" from the list of items.
3. Choose "EF Designer from database" and click "Next."
4. Enter the connection string for the database and click "Next."
5. Select the tables that you want to use in your application and click "Finish."

7. Creating a controller

A controller is responsible for handling requests and returning responses. In Asp.Net, we can easily create a controller using the scaffolding feature. To create a controller, we need to follow these steps:

1. Right-click on the project and select "Add -> New Scaffolded Item."
2. Choose "MVC Controller with views, using Entity Framework" from the list of items and click "Add."
3. Choose the model that you want to use and click "Add."
4. Select the views that you want to generate and click "Add."

8. Creating views

Views are responsible for rendering the data that is returned by the controller. In Asp.Net, we can easily create views using Razor syntax. To create views, we need to follow these steps:

1. Open the controller that we created in the previous step.
2. Right-click on the action method and select "Add View."
3. Choose the type of view that you want to create and click "Add."

9. Running the application

Once we have created the model, controller, and views, we can run the application and test it. To run the application, we need to follow these steps:

1. Press F5 or click on the "Debug" button in Visual Studio.
2. The application will be launched in the web browser.

10. Deploying the application

Once we have tested the application locally, we can deploy it to a web server. To deploy the application, we need to follow these steps:

1. Right-click on the project and select "Publish."
2. Choose the type of deployment that you want to use and click "Next."
3. Enter the connection details for the web server and click "Next."
4. Choose the files that you want to deploy and click "Publish."

11. Conclusion

In this article, we have provided a step-by-step guide on how to build a basic web application with Asp.Net. We have covered everything from setting up the development environment to deploying the application to a web server. By following these steps, you can create a robust and reliable web application using Asp.Net.
