MVC4 -> MVC5 업그레이드 후 증상별 조치
1. *.cshtml 에서 html.helper들에서 빨간 줄 보일 때
//View 폴더 안에 web.config 전체에 해당 함. 폴더 별 수정 필요.
/Views/web.config
Mvc 참조는 4.0.0.0 -> 5.2.3.0
page , razor 참조는 2.0.0.0 -> 3.0.0.0
으로 버전 변경해야함.
이전 버전으로 설정된 상태로 있기 때문이고 현재 버전이 적용되지 않음.
2. ViewBag 이 정의되지 않았다고 error list 에 표시 될 때
C:\Users(사용자)\(로그인계정)\AppData\Local\Temp\Temporary ASP.NET Files
임시폴더 내용 삭제
solution clean > solution rebuild > start
