  1. Download and Install

    To start building .NET apps you just need to download and install the .NET SDK (Software Development Kit) for Windows.

  2. Create your app

    Open a new command prompt and run the following commands.

    dotnet new console -o myApp
    cd myApp

    The dotnet command will create a new application of type console for you. The -o parameter will create a directory named myApp where your app will be 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 is 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!");
            }
        }
    }
  3. Run your app

    In your command prompt, run the following command:

    dotnet run

    Congratulations, you've built and run your first .NET app!

  4. Get an editor

    Visual Studio is a fully-featured integrated development environment (IDE) for developing .NET apps on Windows.

    Download Visual Studio

    Select the .NET Core cross-platform development workload during installation:

  5. Keep learning

    While you wait for Visual Studio to install, you can keep learning with the .NET Quick Starts. In the first Quick Start you'll learn about collections.

    Once Visual Studio is installed, come back and build your first .NET app using Visual Studio.
