MVC - strongly typed views are broken

So I wrote a custom web control in MVC, and I did the whole csc thing to create a dll out of it.

That didn't work, but when I removed it and everything. My MVC thing broke, and it's giving me this error:

Parser Error Message: Could not load type 'System.Web.Mvc.ViewPage'.

for this line:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" 
    Inherits="System.Web.Mvc.ViewPage<List<className>>" %>

It's not liking strongly typed view now (normal views are working okay)! I'm not registering the dll anywhere anymore. I deleted the dll from bin. I even got rid of the class.

Check your web.config for this assembly line under compilation:

<compilation debug="true" targetFramework="4.0">
  <assemblies>
    <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken="gibberish" />
  </assemblies>
</compilation>
