C # EventLog appender does not write to event log viewer

Question

I need to make my C # application write a log to a Windows event viewer.

I used,

<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender" > <param name="ApplicationName" value="DataLoader" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value='{"Processed":"%d{yyyy-MM-dd HH:mm:ss}","Loglevel":"%p","Service":"DataLoader","Instance":"","AdditionalInfo":"%c{1}|%M","logtext":"%m%n"}'/> </layout> </appender> 

There are no errors in the console, but it does not write logs to the Windows Event Viewer
