See list
Install the NLog.Windows.Forms NuGet package and register the extension-assembly.
NLog will only recognize the extensions when loading from NLog.config-file, by adding the extension to NLog.config-file:
<extensions>
<add assembly="NLog.Windows.Forms"/>
</extensions>
Alternative register from code using fluent configuration API:
NLog.LogManager.Setup().RegisterWindowsForms();
