Answer 1

I have same problem yesterday when I convert my old 3.0 project to MVC 4. in 2013 ViewBag and something also not found in current context even it's work fine in browser.

Make a new app with same namespace and copy paste the stuff carefully. After doing this your project will work like a charm.
