Hello,
Whenever i make an MVC 5 controller with views, using entity framework and try to run and compile the file i get the "your sql server installation is either corrupt or has been tampered with (unknown package id)." I've reinstalled Vs 2013, and have already reinstalled and uninstalled 2012/2014 versions of microsoft SQL local db.
If anyone has encountered and knows a fix to the issue it would be greatly appreciated.
