First C# Program

Steps to Create the Program

1. Open Visual Studio (or your preferred IDE).

2. Create a New Project:

  1. Select Console App (.NET Core) or Console App (.NET Framework) depending on your setup.
  2. Give your project a name (e.g., HelloWorldApp).

3. Write the Program in the main file (usually Program.cs).

Example:


//Program.cs file
using System;

class Program
{
    static void Main(string[] args)
    {
        // Print "Hello, World!" to the console
        Console.WriteLine("Hello, World!");
    }
}

Note: Press Ctrl + F5 (or click Start in Visual Studio) to run the program

Output:

Hello, World!

Explanation:

1. using System: This line imports the System namespace, which includes essential classes like Console used to interact with the console.

2. class Program: Defines a class called Program. In C#, every program must have at least one class.

3. static void Main(string[] args): This is the Main method, the entry point of every C# console application. When you run the program, the Main method is executed first.

4. Console.WriteLine(“Hello, World!”): This line prints the text “Hello, World!” to the console.
