Hi Vladimir Yes, you're correct that the event log appender isn't available in the netstandard version of log4net because it's not cross-platform. Right now, I don't have capacity to build one (I have outstanding work I'd like to do in log4net as it is), so the best suggestions I can give are: If Log4Net.Appenders.NetCore still works adequately, then use it. Windows event logging has pretty-much stayed the same for many years and is unlikely to change because it would break a lot of things. Since the code is open-source, you could choose to use the nuget package (though you may have to implement assembly bindings) or you could copy-paste the code from https://github.com/robsonj/Log4Net.Appenders/blob/master/Log4Net.Appenders.NetCore/EventLogAppender.cs into your project. Licensing appears to be MIT from the csproj, though there's no LICENSE file in the repo. There's also a fork at https://github.com/JTOne123/Log4Net.Appenders which was updated a little more recently. You could contribute, either by helping to revive Log3Net.Appenders.NetCore, or by creating a new package - the smaller and more accurately-named, the better, so I'd suggest something like Log4Net.EventLogAppender.NetCore - with only this appender in it and get that up at nuget.org. Sincee it brings in the extra package reference for System.Diagnostics.EventLog, I wouldn't want to include this directly in log4net, forcing more package dependencies than many people would want. Indeed, this is how I was first introduced to working with log4net - I wrote https://www.nuget.org/packages/Chillisoft.splunk4net, which isn't maintained any more because I left the company and it's their project (and I don't use splunk any more either). However, it's an example of what you could do.
