Question

由于文件夹删除，我在应用程序池重启时遇到了一些麻烦，所以我想我会尝试禁用fcnMode（这里描述：Application Restart for folder deleted,added,updated）。

我尝试使用注册表，并将其设置为1. Web应用程序将再次启动...我也尝试了2，Web启动但文件夹删除问题仍然存在。 2并没有禁用FCN所以我猜它是预期的。

然后我尝试在web.config中使用.NET 4.5新的fcnMode值：

这与将注册表项设置为1具有完全相同的效果。

在这里你可以看到我遇到的问题。

对不起，如果我浪费了某些人的时间，但突然之间它的工作正常。我意识到我没有在调试模式下运行，这就是为什么我没有看到更好的堆栈跟踪。

最合乎逻辑的假设一定是人（好吧，我）因素。可能会把双重httpRuntimes或其他东西。

所以 - 再也没有错误了。但是没有解决原始问题，如下所述：ImageResizer restarts application pool

Web无法启动fcnMode设置为禁用
