[A]System.Web.WebPages.Razor.Configuration.HostSection cannot be cast to… web.config issue

Question

I am getting the following error:

[A]System.Web.WebPages.Razor.Configuration.HostSection cannot be cast to [B]System.Web.WebPages.Razor.Configuratio

Answer 1

In my case, I've solved this by also updating the Web.config on the live server which the VS has updated upon upgrading to MVC 5
