MVC ViewBag Best Practice

Question

For the ViewBag, I heard it was a no-no to use. I would assume have the content from the ViewBag should be incorporated into a view model?

Question:

1. <

Answer 1

The issue with ViewBags and the recommended best practice boils down to compile time checking. ViewBags are just dictionaries and with that you get 'magic' strings, so if you end up changing the object type of one of the viewbag items or the key name you won't know until runtime, even if you precompile the views using true.

Sticking to view models is best, even if you have to alter them to fit a specific view now and again.
