Estou usando log4net no meu projeto ASP.NET MVC3, mas todas as propriedades de log comoIsDebugEnabled == false

Na minha AssemblyInfo eu tenho:

[assembly: XmlConfigurator(Watch = true)]

Na minha classe de log eu tenho

public Log4NetLogger()
{
    log4net.Config.XmlConfigurator.Configure();
    Logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
}

O meu material de configuração relacionado no Web.Config é:

</configuration>

Eu já fiquei frustrado a ponto de querer fazer

public Log4NetLogger()
{
    Logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);


    Logger.IsDebugEnabled = true;
}

No entanto, é claroLogger.IsDebugEnabled não possui setters: /

O que eu preciso fazer para que essa maldita coisa funcione?
