    How to Install C# on Ubuntu 22.04 and Getting Started

    C# is a strong-typed, multi-paradigm programming language developed by Microsoft as part of the .NET platform.

    Its syntax is object-oriented and was based on C++ but includes many influences from other programming languages, such as Object Pascal and, mainly, Java.

    In this article we will see how to install on Ubuntu 22.04, however, you can adapt the instructions for any other version or even another distribution.

    Installation

    Before installing, register the keys:

    wget https://packages.microsoft.com/config/ubuntu/21.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

    Now install the key:

    Tip: execute one command at a time, if your Ubuntu version is different, find 22.04 for the version corresponding to yours. See here all available versions.

    sudo apt-get install -y gpg
wget -O - https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor -o microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget https://packages.microsoft.com/config/ubuntu/22.04/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list

    Now install the SDK, runtime will also be installed automatically

    sudo apt-get update; \
  sudo apt-get install -y apt-transport-https && \
  sudo apt-get update && \
  sudo apt-get install -y dotnet-sdk-6.0

    You can now clean the file: packages-microsoft-prod.deb

    rm packages-microsoft-prod.deb

    Testing a Hello, World!

    1. Create a project

    dotnet new console -o MyApp

    If you want to specify the version, use: dotnet new console -o MyApp -f net6.0

    2. Enter the project:

    cd MyApp

    3. Edit the Program.cs file

    Change the output as you wish, example:

    Console.WriteLine("Hello, C Sharp via Ubuntu 22.04!");

    Now run it at runtime:

    dotnet run

    Note that it will take a while to run, as it was compiled and then executed. If you want to separate tasks:

    First build:

    dotnet build

    The likely and similar output will be:

    Microsoft(R) Build Engine version 17.1.1+a02f73656 for .NET
