  </configSections>

  <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <targets>
       <target xsi:type="File" name="f" fileName="${basedir}/APP_Data/logs/${shortdate}.log" layout="${longdate} ${uppercase:${level}} ${message}" /> 
    </targets>
    <rules>
       <logger name="*" minlevel="Trace" writeTo="f" />
