.net - Log4net won't log to console (WinForms app)

Question

I'm just starting using the Log4Net library and having problems configuring it. I don't need anything special. I'm using it for a Winforms application and need basic file and console logging. To keep it as simple as possible, I'm using the App.config for configuration and using the default values taken from Log4Net project website: App.config:

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="ProjectFolder" value="D:Documentsmy documentsThemisProjects"/>
  </appSettings>
  <configSections>
    <section name="log4net"
       type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>
  <log4net>
    <appender name="LogFileAppender" type="log4net.Appender.FileAppender">
      <param name="File" value="ThemisLog.txt" />
      <param name="AppendToFile" value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="Header" value="[Header]
" />
        <param name="Footer" value="[Footer]
" />
        <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" />
      </layout>
    </appender>

    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
      <layout type="log4net.Layout.PatternLayout">
        <param name="Header" value="[Header]
" />
        <param name="Footer" value="[Footer]
" />
        <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" />
      </layout>
    </appender>

    <root>
      <level value="DEBUG" />
      <appender-ref ref="LogFileAppender" />
      <appender-ref ref="ConsoleAppender" />
    </root>
  </log4net>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup></configuration>

Program class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using log4net;
using log4net.Config;

[assembly: log4net.Config.XmlConfigurator(Watch = true)]
namespace Themis
{
    static class Program
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(Program));

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            log4net.Config.XmlConfigurator.Configure();

            log.Debug("Enter application");
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new OldFrmMain());
            log.Debug("Exit application");
        }
    }
}

The log file is created and logs are created into it, but no console logging happens.

What you want is not ConsoleAppender but TraceAppender.

The name can be confusing, but TraceAppender writes in Visual Studio's "Output" window.

Sample:

<log4net>
  <appender name="TraceAppender" type="log4net.Appender.TraceAppender">
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%d [%t] %-5p %c %m%n"/>
    </layout>
  </appender>

  <root>
    <level value="ALL"/>
    <appender-ref ref="TraceAppender"/>
  </root>
</log4net>
