[sunjester tuts] Using C# (.NET code/apps) on Linux - sunjester - 03-11-2019

Introduction
All of my tutorials are written, tested, and meant to be used on Linux. I am using Ubuntu xenial (currently 16.04). You can use any debian distro and follow any of my tutorials. I will not pander to the Windows kiddies, don't ask.

Directions
First, let's check what version you have, you can use the lsb_release command.

Code:
lsb_release -a

18.04

Code:
sudo apt install gnupg ca-certificates
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb https://download.mono-project.com/repo/ubuntu stable-bionic main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update

16.04

Code:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
sudo apt install apt-transport-https ca-certificates
echo "deb https://download.mono-project.com/repo/ubuntu stable-xenial main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update 

14.04

Code:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
sudo apt install apt-transport-https ca-certificates
echo "deb https://download.mono-project.com/repo/ubuntu stable-trusty main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update

Next, install Mono

Code:
sudo apt install mono-devel

Now we can compile and then run the C# code below, that i've saved in a file named hello.cs

Code:
using System;
 
public class HelloWorld
{
    static public void Main ()
    {
        Console.WriteLine ("Hello World");
    }
}

using the csc to compile
csc hello.cs

and using mono to run the .net executable
mono hello.exe

WinForms
You can compile the winforms applications using the following argument

Code:
-r:System.Windows.Forms.dll

Gtk# Forms

Code:
-pkg:gtk-sharp-2.0

Well mono is kind of obsolete, when .NET Core is out with UI libraries going to be release really soon + here is AvaloniaUI for impatient.

.net core has been out for quite some time. Mono is simply the runtime. Unless you're not using any dependencies, then you'll need it.

mono is an IDE for building .net applications on linux, it's not obsolete.

The only thing VB has going for it is the basic syntax if you grew on it so it has a sorta nostalgic value ("muh goto").
