[Mono-devel-list] Mono app x services

[A Rafael D Teixeira]

Well, depending on what is needed I would make just a shell script, like:

#!/bin/sh
nohup mono mydaemon.exe > /tmp/mydaemon.log 2>&1 &

Comments: nohup makes it not be killed when the console session terminates 
and "2>&1" redirects stderr to stdin what makes it completely silent (all 
output goes to the log file).

If needed a more sofisticated construction could follow this Java Daemon 
solution
