Wix + log4net: Windows service not logging after service is installed

Question

I'm trying to create a Windows Service which will use log4net to log all the service's actions. This service will be installed using Wix.

I've tried almost everything already but I'm still stuck in a problem. The service is installed and is running but log4net is not generating any log files (I'm writing to .txt files). Here is my files:

Inside App.config

<configSections>
    <!-- Log4net config section -->
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false" />
  </configSections>

  <log4net debug="true">    
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Logs\.log" />
      <appendToFile value="true" />
      <rollingStyle value="Composite" />
      <datePattern value="dd_MM_yyyy" />
      <preserveLogFileNameExtension value="true" />
      <staticLogFileName value="false" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%newline%date{dd/MM/yyyy HH:mm:ss} [%thread] %level %property{log4net:HostName} - %property{log4net:UserHostAddress}: %logger - %message %newline" />
      </layout>
    </appender>
    <root>
      <level value="INFO" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
  </log4net>

AssemblyInfo.cs

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

Service1.cs

protected override void OnStart(string[] args)
{
    log4net.ILog logger = log4net.LogManager.GetLogger(typeof(Service1));

    logger.Info("Service Started");

    this.timer = new Timer();
    this.timer.Elapsed += new ElapsedEventHandler(this.timerLog_Tick);
    this.timer.Interval = 6000;
    this.timer.Start();
}

</Wix>

When the service is installed these are in the folder:

1. .config file
2. log4net.dll and log4net.xml
3. .exe file (service)

When I run the service using Visual Studio, the log is created inside the "Logs" folder correctly.

I tried giving permission on the installed folder to "Everyone", no success. I even tried to create the "Logs" folder and give permission to it, also didn't work.

I searched a lot and couldn't find nothing regarding wix + log4net. It seems to me that it is something with Wix but I really don't know what it is.

Answer 1

I think the problem is that the current directory is not what you think it is. I believe if the application runs as a service the current directory is the system32 folder, but I did not verify this now.

If you try to use an absolute path (with correct permissions) in your configuration then it should work as expected.
