[Mono-dev] Event logging under Mono

I'd just use a proper logging framework like NLog (http://nlog-project.org/) instead of using the rather Windows-specific event log implementation.

[Sorry if duplicate. I think I originally sent to wrong alias]
Hi –
I am trying to implement logging for a small application running under Mono on a Raspberry Pi. Unfortunately I have been unable to create an event log despite following guidance that I have found on the Net,
 and am wondering if there is best practice on how to do this. FWIW, the steps I have taken are as follows:
On the Raspberry Pi, I created /var/lib/mono and /var/lib/mono/eventlog directories, set directory permission on each to 777 per

Ran the following .NET code, based loosely on

using System;
using System.Text;
using System.Diagnostics;

namespace Logging
    class Program
        static void Main(string[] args)
            if (!EventLog.SourceExists("MySource"))
                EventLog.CreateEventSource("MySource", "MyNewLog");
                Console.WriteLine("Exiting, execute the application a second time to use the source.");
                Console.WriteLine("Found the EventLog Source.");
If I run this twice on a Windows 8 machine, the first time it comes back with “CreatedEventSource”, the second time it comes back with “Found the EventLog Source”, and the Windows Event Log has a new log entitled
 MyNewLog. However, if I run it on the Raspberry Pi under mono, I get the message “CreatedEventSource” no matter how many times I run it, and no files are created in /var/lib/mono/eventlog.
What am I missing, or what should I try instead?
