I am trying to use ViewBag in my application, I have all of the recent dlls, the latest version of MVC 3, but yet I am still getting the Error:
"The name 'ViewBag' does not exist in the current context"
I have even uninstalled and then re-installed MVC 3 and yet there is no change.
Also, I do not believe that the dll's are showing up in the GAC.
What might be my problem? Or how to add the dll's to the GAC?
You need to add the MVC-specific Razor configuration to your web.config. See here: Razor HtmlHelper Extensions (or other namespaces for views) Not Found
Use the MVC 3 upgrade tool to automatically ensure you have the right config values.
