HTTP Error 500.19 - Internal Server Error localhost

Question

newbie here, I am having an error in all of my projects and backups when executing my project visual studio 2012. Last week it was working fine and then the error came out. I am just using localhost.

these are solutions that i found and it still didn't work: :(

-In IIS Manager - Feature Delegation set HandlerMapping to Read/Write.

-Control Panel, Turn windows features on or off, Internet Information Services, World Wide Web Services, enable Application Development Features except CGI.

-I gave IIS_IUSRS full control to my project folder.

Any other suggestions?

根据我的说法，您的应用程序池中应该有问题。.只需更改并选择适当的version 4.5池即可解决您的服务器问题。.如果仍然无法解决您的问题，请告知。
