Mono is an open source, cross-platform, implementation of C# and the CLR that is binary compatible with Microsoft.NET.

The Arch Linux packages of mono have activated the experimental .NET 4.0 features, but be aware that it may not be stable. Those features are only for developers, so if you just want to use Mono to run applications, then you won't be affected by this.


First install mono with pacman:

# pacman -S mono

If you need VisualBasic.Net support you have to install the VisualBasic.Net interpreter:

# pacman -S mono-basic

Registering Mono Applications with the Kernel

You can execute binaries by calling mono manually

mono programsname.exe

It is also possible to tell the kernel to use mono as an interpreter for all Mono binaries. To this, just add mono to your DAEMONS array in /etc/rc.conf and it will automatically be setup for you.

DAEMONS=( ..... mono .... )

Now try this:

chmod 755 exefile.exe

Testing Mono

Make a new file; test.cs

using System;

public class Test {
 public static void Main(string[] args) {
  Console.WriteLine("Hello World!");

Then run:

$ mcs test.cs
$ mono test.exe
Hello world!


Starting to develop in Mono/C# is very easy. Just install the MonoDevelop IDE and debugger support with pacman:

# pacman -S monodevelop monodevelop-debugger-gdb monodevelop-debugger-mdb

If you want the API documentation browser and some testing and development tools you have to install mono-tools:

# pacman -S mono-tools
