So I want to organize my project and I've made a subfolder with all my configuration files. I've noticed that when I move NLog.config to this subfolder it wont work. Has anybody noticed this behaviour? I'd like to learn why it worked like that.
As by this github thread, this should work if you put it in you app.config:
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" autoReload="true">
<include file="Config\NLog.config"/>
</nlog>
As mentioned by comment, you need to include the nlog section as well, here's the full snippet:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
</sectionGroup>
<section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog" />
</configSections>
<common>
<logging>
<factoryAdapter type="Common.Logging.NLog.NLogLoggerFactoryAdapter, Common.Logging.NLog32">
<arg key="configType" value="INLINE" />
</factoryAdapter>
</logging>
</common>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" autoReload="true">
<include file="Config\NLog.config"/>
</nlog>
</configuration>
