C# Hello World | Your First C# Program

Following is an explanation of the steps to create your first C# program "Hello World":

Install and set up the development environment

The first step is to install a C# development environment such as Visual Studio or Visual Studio Code. Once installed, open the development environment and create a new console application project.

Write the code

Once you have created the project, you can write the "Hello World" code. In C#, this is a very simple program that outputs the text "Hello, World!" to the console.

using System; class Program { static void Main() { Console.WriteLine("Hello, World!"); } }
//Output: Hello, World!

This code does the following:

  1. The using System; statement is used to include the System namespace, which contains the Console class that we will use to output the text.
  2. The class Program line defines a new class called Program.
  3. The static void Main() method is the entry point for the program, and it is where the program starts executing. It is a static method, which means that it can be called without an instance of the Program class.
  4. The Console.WriteLine("Hello, World!"); line outputs the text "Hello, World!" to the console.

Build and run the program

Once you have written the code, you can build and run the program. In Visual Studio, you can do this by clicking the "Start" button or by pressing F5. The program will run, and you will see the text "Hello, World!" printed to the console.
