C-Sharp Programming - Hello World

C-Sharp Programming - C# (pronounced C sharp) is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines.

It was developed around 2000 by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018). C# is one of the programming languages designed for the Common Language Infrastructure.

C# was designed by Anders Hejlsberg, and its development team is currently led by Mads Torgersen. The most recent version is C# 7.3, which was released in 2018 alongside Visual Studio 2017 version 15.7.2.

To create and run a console application

1. Start Visual Studio.

3. Expand Installed, expand Templates, expand Visual C#, and then choose Console Application.
4. In the Name box, specify a name for your project, and then choose the OK button.
   The new project appears in Solution Explorer.
5. If Program.cs isn't open in the Code Editor, open the shortcut menu for Program.cs in Solution Explorer, and then choose View Code.
6. Replace the contents of Program.cs with the following code.

   // A Hello World! program in C#.
   using System;
   namespace HelloWorld
   {
       class Hello 
       {
           static void Main() 
           {
               Console.WriteLine("Hello World!");
   
               // Keep the console window open in debug mode.
               Console.WriteLine("Press any key to exit.");
               Console.ReadKey();
           }
       }
   }
   

7. Choose the F5 key to run the project. A Command Prompt window appears that contains the line Hello World!
