I won’t go too much into the details of my project, but I am implementing simple logging into a .txt file. I am using NLog as a provider. My issue resides with the nlog.config file:

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      internalLogFile="c:tempinternal-nlog-AspNetCore.txt">

    <extensions>
        <add assembly="NLog.Web.AspNetCore" />
    </extensions>

    <targets>
        <target xsi:type="File" name="auditlog" filename="{basedir}LogsMain${shortdate}.txt" layout="[ApiAuditLog] | Logger: ${logger} | ${time} | Details: ${message}" />
        <target xsi:type="File" name="servicelog" filename="{basedir}LogsMain${shortdate}.txt" layout="[ServiceLog] | Logger: ${logger} | ${time} | Details: ${message}" />
        <target xsi:type="File" name="exceptionfile" filename="{basedir}LogsExceptions${shortdate}.txt" layout="[ExceptionLog] | Logger: ${logger} | ${time} | Details: ${message}"/>/>
    </targets>

    <rules>
        <logger name="Microsoft.*" maxLevel="info" final="true" />
        <logger name="GameStore.API.Middlewares.RequestResponseLoggingMiddleware*" minlevel="Info" writeTo="auditlog" final="true"/>
        <logger name="GameStore.BLL.Services*" minlevel="Info" writeTo="servicelog" final="true"/>
        <logger name="*ExceptionHandlingMiddleware*" minlevel="Error" writeto="exceptionfile" />
    </rules>
</nlog>

The issue is that the auditlog does not get logged, even though I checked with the debugger, and the ILogger instance itself is enabled.

I all sorts of stuff. I tried removing everything else from the nlog.config file and leaving only the details for the auditlogging. I tried only passing a test string to the ILogger instance (usually it takes a json formatted string). I tried rewiring the namespaces….
