MVC3 Views unable to find added referenced class

My view is having issues finding a class located in one of my references. This reference is to a dll built outside of the project.

The view always gives error:

The type or namespace name 'Company' could not be found (are you missing a using directive or an assembly reference)

Here is the controller. No issues there.

using Company.Entities;

public ActionResult Find()
{
    Person test = Person.SelectByADDistinguishedName("L*", false);
    return View(test);
}

Here is the View. The error occurs in the @Model line.

@model Company.Entities.Person

@{
    ViewBag.Title = "Bob";
}

Find

My Views/Web.config currently looks like this

I've checked similar threads like this one but to no avail.

Here is the message on the screen

Line 25: using System.Web.Mvc.Html;
Line 26: using System.Web.Routing;
Line 27: using Company.Entities;
Line 28: 
Строка 29:

If I strip out any mention of the assembly (out of web.config - no @using statments). I get the same error message when loaded but against this line

public class _Page_Views_Home_Find_cshtml : System.Web.Mvc.WebViewPage {
