Я занимаюсь разработкой C # .NET Core 2.2 Web-Api на Visual Studio 2017 .Я реализую NLog 4.6.1, как описано в github .Когда я запускаю свое приложение, используя IIS , NLog не записывает в Elasticsearch .Ошибка возникает в строке в program.cs
var logger = NLog.Web.NLogBuilder.ConfigureNLog("NLog.config").GetCurrentClassLogger();
Я нахожу сообщение об ошибке в NLogError.log :
2019-06-12 09:00:49.1606 Error Penter code herearsing configuration from NLog.config failed. Exception: NLog.NLogConfigurationException: Exception when parsing NLog.config. ---> System.ArgumentException: Target cannot be found: 'EventLog'

Я попытался сократить мой конфигурационный файл, чтобы избежать других проблем, но все еще та же ошибка.Цель "EventLog" - найти там.
NLog.config:
<?xml version="1.0" encoding="utf-8" ?>
<nlog autoReload="true" throwExceptions="false"
internalLogLevel="Error" internalLogFile="NLogError.log"
xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<targets>
<target name="EventLog" xsi:type="EventLog"
layout="${longdate} ${level} ${callsite} -> ${message}
${exception:format=Message,StackTrace}"
source="MonDBSvc" />
</targets>
<rules>
<logger name="MonDbSvc" minlevel="Error" writeTo="EventLog"
log="Application" />
</rules>
</nlog>
Файл NLog.config и файл program.cs находятся на одном корневом уровне в папке приложения..
Я пытался написать NL og.config nad nl og.config для имени файла и в этом кодестрока выше.
Что может вызвать эту проблему синтаксического анализа?Что я могу попытаться исправить?
Спасибо за поддержку!
Когда я изменяю уровень журнала с ошибки на предупреждение, я получаю более явное сообщение.Я уверен, что XML действителен как XML.
