Asp.Net Mvc 2 Areas Tip: Drop in a web.config
I ran into an exception “Could not load type ‘System.Web.Mvc.ViewPage
So if you are coming up against this issue, you might be having that same issue.
The solution, drop in a copy of the web.config from the views folder into the folder for your areas folder (i.e. Areas/AreaName or Areas/AreaName/Views). Refresh. That should solve that exception. Hopefully.
