Package Management

  • Most Linux distributions use a package manager
  • Everything is a package - from your kernel to the software that you use
  • Debian-based distributions use apt

Installation

  • We have the apt repository
  • Now we can install Mono
  • sudo apt install mono-devel

Usage

  • If you've got some C♯ code in a Visual Studio solution already, download that now
  • Otherwise, use a text editor to write a quick program
  • On Linux, we can use csc and msbuild just like we do on Windows
