I created small startup script for launch Manager as a service on boot time. It uses Upstart system, which is available by default.
create file /etc/init/manager.conf
description "Manager.IO launch" #start on filesystem start on runlevel  stop on runlevel [!2345] #task script exec sudo /usr/bin/mono /home/username/ManagerServer.exe -port 80 end script
This allows you to start server by command
and to stop with
Also manager will start after system boot. In my case ManagerServer was extracted to home directory of “username”.
