NLog not logging the exception or any other text - asp.net-mvc

Question

Here is my Nlog.Config code.
<nlog>
<variable name="logFilePath" value="C:\NLog\IDG-${shortdate}.log" />
<targets>
<target name="logfile"
xsi:type="File"
fileName="${logFilePath}"
layout="${longdate} LEVEL=${level:upperCase=true}: ${message}"
keepFileOpen="true" />
</targets>
<rules>
<logger name="*" minlevel="Debug" writeTo="logfile" />
<logger name="*" minlevel="Info" writeTo="logfile" />
<logger name="*" minlevel="Warn" writeTo="file"/>
</rules>
</nlog>
and am defining this in my class
private static Logger logger = LogManager.GetCurrentClassLogger();
and then I'm logging the error as:
catch (Exception ex)
{
logger.Error(ex.Message,"test");
}
Can anyone please suggest me if there is any better way to do this, I don't see the file logging in the destined folder.

It seems that you may not be referencing the config section correctly. Try changing your main config file to something like this and remove the Nlog.Config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog" />
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.2" />
</startup>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<variable name="logFilePath" value="C:\temp\output.log" />
<targets>
<target name="logfile"
xsi:type="File"
fileName="${logFilePath}"
layout="${longdate} LEVEL=${level:upperCase=true}: ${message}"
keepFileOpen="true" />
</targets>
<rules>
<logger name="*" minlevel="Debug" writeTo="logfile" />
<logger name="*" minlevel="Info" writeTo="logfile" />
<logger name="*" minlevel="Warn" writeTo="file"/>
</rules>
</nlog>
</configuration>
