  <targets>
    <target name="file" xsi:type="File" fileName="logs/app.log" />

    <logger name="*" minlevel="Debug" writeTo="file" />
  </rules>
</nlog>

logger.Info("This is an info message");

Can I log to multiple targets?

Yes, you can log to multiple targets by defining them in your NLog.config file and specifying them in the rules. For example, you can log to both a file and the console.
