Hi,
I have used log4net before where there was no need to write any code just do some configuration in config file to log the errors. Now i want to do same using Nlog but couldnt achieve this . Can some show me sample how to log using Nlog. I tried below code in config file

<nlog>
    <targets>
      <target name="file"  layout="${longdate} ${logger} ${message}" filename="${basedir}/logs/logfile.txt" xmlns:xsi="#unknown" />
    </targets>
   <rules>
        <logger name="*" minlevel="Off" writeto="file" />
    </rules>
  </nlog>

and tried to raise error in controller but its not creating log file. Is anything wrong in above code
