IIS上的WCF log4net与AdoNetAppender无法正常工作

Question

我正在尝试在一个要托管在IIS上的wcf服务中配置log4net，目前正在使用iis express ...问题是我无法在数据库中记录这些值。我正在使用.net 4.0和wshttpbinding为wcf。

我已经通过一些文章并将buffersize设置为1.并且还启用了调试..但没有任何反应：（

这是我的服务web.config

  </system.diagnostics>

</configuration>

这就是我的代码

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
    public class IVR : IIVR
    {
        private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
}

我不确定这有什么问题？请帮忙
