Create your app

In your command prompt, run the following commands:

In your terminal, run the following commands:

dotnet new console -o myApp
cd myApp

The dotnet command creates a new application of type console for you. The -o parameter creates a directory named myApp where your app is stored, and populates it with the required files. The cd myApp command puts you into the newly created app directory.

The main file in the myApp folder isĀ Program.cs. By default, it already contains the necessary code to write "Hello World!" to the Console.

using System;

namespace myApp
    class Program
        static void Main(string[] args)
            Console.WriteLine("Hello World!");
