  1. Add the dotnet product feed

    To start installing .NET, you'll need to register the Microsoft signature key and add the Microsoft Product feed. This only needs to be done once per machine.

    Open a command prompt and run the following commands:

    sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
    sudo sh -c 'echo -e "[packages-microsoft-com-prod]\nname=packages-microsoft-com-prod \nbaseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/dotnetdev.repo'
  2. Install the .NET SDK

    Update the products available for installation, install the components required by .NET, then install the .NET SDK.

    In your command prompt, run the following commands:

    Fedora 26 or more recent:

    sudo dnf update
    sudo dnf install libunwind libicu compat-openssl10
    sudo dnf install dotnet-sdk-2.0.2

    Other versions:

    sudo dnf update
    sudo dnf install libunwind libicu
    sudo dnf install dotnet-sdk-2.0.2
  3. 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!");
            }
        }
    }
  4. Run your app

    In your command prompt, run the following command:

    dotnet run

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

  5. Get an editor

    Visual Studio Code is a free, cross-platform code editor with support for .NET.

    Download Visual Studio Code

    For full language support including smart code completion and debugging, get the C# extension for Visual Studio Code.

    Download the C# Extension

    There are also third party tools for developing .NET apps. JetBrains Rider is a cross-platform .NET IDE built using IntelliJ and ReSharper technology.

  6. Keep learning

    Now that you've got the basics, you can keep learning with the .NET Quick Starts. In the first Quick Start you'll learn about collections.
