Q:在IIS上部署web后，游览器打开报以下异常：
This configuration section cannot be used at this path.
This happens when the section is locked at a parent level.
Locking is either by default (overrideModeDefault="Deny"),
or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
A:IIS安装developmnet后重启IIS即可。
IIS-This configuration section cannot be used at this path.
