      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
      autoReload="true"
      throwExceptions="false"

    <!-- optional, add some variables
    https://github.com/nlog/NLog/wiki/Configuration-file#variables
    -->
    <variable name="myvar" value="myvalue"/>

    <!--
    See https://github.com/nlog/nlog/wiki/Configuration-file

    -->
    <targets>
      <target xsi:type="File" name="Logfile"
              fileName="${basedir}/Logs/date-${date:format=yyyyMMdd}.log"
              archiveAboveSize="10485760"

• Set up the main class.

  // Import NLog classes.
  using NLog;

  public static class Program
  {
      public static void Main(string[] args)
      {
          Logger logger = LogManager.GetCurrentClassLogger();
          logger = LogManager.GetLogger("Logfile");
          MappedDiagnosticsContext.Set("Message", "Hello NLog");
          logger.Log(LogLevel.Trace, "");
      }
  }
