Sure, here’s a short article on C# basics - Hello World:

C# is a modern, object-oriented programming language developed by Microsoft as part of its .NET initiative. It was designed to work with the .NET Framework and has become one of the most popular languages for building Windows applications.

One of the simplest programs you can write in C# is “Hello World”. This program displays the text “Hello, World!” on the screen when executed. Here’s how you can create a Hello World program in C#:

using System;

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

In this code, we start by using the System namespace which provides various classes and methods that are commonly used in .NET applications. Then, we define a class called HelloWorld. Inside this class, we have a static method called Main, which is the entry point of our program.

The Main method takes an array of strings as its parameter, but we don’t use it in this case. Instead, we call the Console.WriteLine method to display the text “Hello, World!” on the screen. The WriteLine method writes a line of text to the console and then adds a newline character at the end.

To run this program, you need to have Visual Studio or any other C# compiler installed on your computer. Once you’ve set up your development environment, you can compile and execute this code by pressing F5 or clicking the “Run” button in Visual Studio.

When you run this program, you should see the text “Hello, World!” displayed in the console window. This is a simple but important step in learning C# programming as it demonstrates how to write and execute your first C# program.

In conclusion, writing a Hello World program in C# is an excellent way to get started with this language. It’s a basic yet essential skill that will help you build more complex applications using C#. With practice and patience, you can master the basics of C# programming and move on to more advanced topics.
