NLog: LayoutRenderer cannot be found: 'aspnet-user-identity - oracle

Question

I try to implement NLog into my .NET Core Api web service.
I want to log to an Oracle database. All works well through an nlog.config XML file.
But the goal is to implement NLog config into appsettings.json and here problem occurs.
I get the error set in title:
LayoutRenderer cannot be found: 'aspnet-user-identity
My config file is like this :
"NLog": {
"autoReload": true,
"throwConfigExceptions": true,
"internalLogLevel": "info",
"internalLogFile": "c:/app/log/dev/internal-appsetting-nlog.txt",

"maxLevel": "Info",

}
]
},
The internal debugger reports:

at NLog.Internal.PropertyHelper.SetPropertyFromString(Object obj, String propertyName, String value, ConfigurationItemFactory configurationItemFactory)
Error occurs on ${aspnet-sessionid}. If I comment out both layout, everything works well.
I found different things on GitHub issue report but all I tried was a fail.
Could someone help?

Answer 1

The unknown aspnet-user-identity is probably an issue with your extensions:
"extensions": [
{ "assembly": "NLog.Extensions.Logging" },
{ "assembly": "NLog.Web.AspNetCore" }
],
Could you try the above suggestion?
P.S. Updated the wiki to include example of multiple "extensions"
