Microsoft.Extensions.Logging.Log4Net.AspNetCore

Allows to configure Log4net as Microsoft Extensions Logging handler on any ASP.NET Core application.

Thanks to @anuraj for this original blog post.

Example of use

• Install the package or reference the project into your asp.net core application.

• Add the AddLog4Net() call into your Configure method of the Startup class.

using Microsoft.Extensions.Logging;

public class Startup
{
    //...

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        //...

        loggerFactory.AddLog4Net(); // << Add this line
        app.UseMvc();

        //...
    }
}

• Add a log4net.config file with the content:

<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <appender name="DebugAppender" type="log4net.Appender.DebugAppender" >
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
    </layout>
  </appender>
  <root>
    <level value="ALL"/>
    <appender-ref ref="DebugAppender" />
  </root>
</log4net>
