At the time of writing 2.11.2 is the newest version for Mono that I could find. If a newer version of Mono has come out by now, you can probably find it here.

Before installing

Before installing version 2.11.2 I actually had 2.6.7 installed (which doesn’t support .NET 4.0). I am not sure if my installation guide will work without you having done this, so in case you run into problems, run this first;

apt-get install mono-complete
apt-get remove mono-complete

After doing this, the command “Mono -V” actually still showed 2.6.7 as being installed so I’m not exactly sure if any of these files were required to get 2.11.2 to run.

Installation guide

Make might take 30-60 minutes, make-install should be fast

Updated for 3.4.0

This release has a bug (missing file) so one of the below commands creates it

apt-get update
apt-get install -y --force-yes gcc libtool bison pkg-config libglib2.0-dev gettext make bzip2 g++ build-essential

mkdir -p /var/mono-install
cd /var/mono-install

wget http://origin-download.mono-project.com/sources/mono/mono-3.4.0.tar.bz2
tar xvjf mono-3.4.*.tar.bz2
