推荐答案

右键单击wwwroot文件夹->属性->安全选项卡->单击Edit按钮->输入IIS AppPool\DefaultAppPool用户->单击在Check names-> OK->然后将其命名为Write permission.

Right click on the wwwroot folder -> Properties -> Security tab -> Click at Edit button -> Enter IIS AppPool\DefaultAppPool user -> Click at Check names -> OK -> Then give it Write permission.
