偶然间碰到这个错误,找到一个临时的解决办法,真正的原因还不知道是什么,也不知道这种解决方法会不会对以后有什么副作用。

“/”应用程序中的服务器错误。

行 253:      </providers>

行 254:    </roleManager>   

源文件: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config    

解决方法:

按照提示的源文件路径,去找到相应的文件打开,然后把报错的那个节点删除掉。有可能删除掉一个,还会继续报另外一个错误,继续删除,直到不报错为止.

如下内容是我报错附近的内容,红色的部分是我报错的两个节点,我依次删除掉,.NET MVC项目可以正常运行了
