Requirements:

Before we start, make sure that you have the following tools installed on your machine:

  • Visual Studio Code or any other IDE of your choice

If you have not installed the above tools on your machine, please visit the official Microsoft website and download the latest versions of Visual Studio Code and .NET Core SDK.

Steps to Create the Hello World Application:

The following are the steps to create the ASP.NET Core Hello World Application:

Step 1: Create a new project in Visual Studio Code

To start creating the application, first, open Visual Studio Code and create a new project by opening the terminal and typing the following command:

“`dotnet new console -o HelloWorld“`

Here, “HelloWorld” is the name of the project.

Step 2: Add the code to the Program.cs file

Once you have created the project, add the following code to the Program.cs file:
“`
using System;

namespace HelloWorld
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine(“Hello, World!”);
}
}
}
“`
This is the basic code for the Hello World Application that prints “Hello, World!” on the console.

Step 3: Run the application

To run the application, open the terminal and navigate to the project directory by typing:

“`cd HelloWorld“`

Then, type the following command:

“`dotnet run“`

This command will build the project and run the application. You should see the following output on the console:
