.NET Framework Hello World in C#


using System;

class Program
    // The Main() function is the first function to be executed in a program
    static void Main()
        // Write the string "Hello World to the standard out
        Console.WriteLine("Hello World");

Console.WriteLine has several overloads. In this case, the string "Hello World" is the parameter, and it will output the "Hello World" to the standard out stream during execution. Other overloads may call the .ToString of the argument before writing to the stream. See the .NET Framework Documentation for more information.
