C# log4net调试appender在VS2017社区中不工作

我有一个log4net的应用程序已经运行多年了。现在，以前工作的调试追加器不再工作。我最近升级到2017 visual studio社区。不知道这是否有关系

下面是要再次检查的配置

嗯。。。我的错误。右键单击并打开程序输出。除了程序输出，我通常都会打开这些。我想我是赶时间把所有的东西都关掉了。

你能给我看一下吗？与代码一起？您没有定义任何

DebugLogger

，也许这就是问题所在？@puller-在根节点上定义了“DebugAppender”的用法。下一个节点是DebugAppender的定义。这就是定义。听起来很愚蠢，但我也花了一些时间才弄明白。
