🤔 What is C# Programming? #

C# (pronounced "C sharp") is a modern, multi-paradigm programming language developed by Microsoft.

It is designed to be simple, efficient, and type-safe, and is used primarily to build Windows desktop applications, web applications, and games.

C# is an object-oriented language that allows developers to create modular and reusable code, making it easier to maintain and scale large applications.

👴 Who is the Father of C#?

Anders Hejlsberg is considered the father of C#. He is a Danish computer scientist who created C# while working at Microsoft in 1999, with the aim of creating a modern, object-oriented programming language that could be used to build a wide range of applications for the Microsoft ecosystem.

💰 Is C# a open-source?

Yes, C# is now an open-source programming language. The open-source version of C# is called the "Roslyn" compiler, and it is available under the MIT license, which allows developers to use, modify, and distribute the language freely without any legal restrictions.

📄 Hello World in C#

Here's an example of a simple C# program that prints Hello, World! to the console:

HelloWorld.cs

Copied

using System;

class HelloWorld
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello, World!");
    }
}

Let me explain the above code:

This program uses the Console.WriteLine() method to output the message "Hello, World!" to the console.
The Main() method is the entry point of the program, and it is where the program starts running when it is executed.
The using System; statement at the beginning of the program indicates that the program is using classes from the System namespace, which includes classes for working with the console, files, and other system-related tasks.
