Trying to find a solution I read this question: What does the Web.Config file do in the views folder of a MVC project
But I still want to know: Why do I need a web.config in all view folders in MVC?
This answer The web.config file exists in the Views folders to prevent access to your views by any means other than your controller is not enough for me, if it's true, it's a temporary solution.
If this is really the only reason, this is a huge point to improve. But, I'm pretty sure there is a good reason for that.
