"Unknown element" in Strongly typed View with Generic Model

Question

I am having trouble defining generic models in razor views. Whenever I use a generic model, I get the following warning:

Unknown element 'string' or element cannot be placed here.

Example:

@model List<string>

While this doesn't cause any major errors, it's still very annoying. Is there a way to define a generic in a razor view that doesn't cause this warning?

Environment: VS 2013
ASP.NET MVC v5.1.2
Razor 3.1.1

I was having the same problem, and it turns out that when I upgraded to the latest version of MVC, not all of my config elements were updated correctly. Changing Web.config in the following ways fixed this for me:

1. Make sure any line mentioning System.Web.Mvc has the version number changed to 5.0.0.0.
2. Make sure any line mentioning System.Web.WebPages.Razor has the version number changed to 3.0.0.0.
