Could not load type 'System.Web.Mvc.ViewMasterPage<dynamic>'.?

I am deploying 开发者_如何学Ca Asp.Net MVC 2.0 application on IIS 6.0. When I request any page I get the following error.

Parser Error Message:
Could not load type 'System.Web.Mvc.ViewMasterPage<dynamic>'.

Source Error:

Line 1:  <%@ Master Language="C#" Inherits=
                   "System.Web.Mvc.ViewMasterPage<dynamic>" %>

Line 2:  <%@ Import Namespace="Combres.Mvc" %>
Line 3:  

Source File: /myApp/Views/Shared/Site.Master Line: 1

are you missing the Views/web.config file?
