ASP.NET MVC 3 Project published only works with all project files

I have been publishing my MVC3 project to IIS including "All Project Files", this has been working fine, but when I changed it to "Only files needed to run this application", the project published fine, but if I try and browse the site in IIS, I get this error.

Parser Error Description: An error occurred durin开发者_StackOverflow中文版g the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

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

Source Error:

Line 1: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>

I remember that I read something a while ago about issues with deploying web projects that only have files required to run it and that by including all source code it works.

I am including the .mvc, .routing, .abstraction dll's as copy local in project.

Has anybody else come across this issue? I cannot find anything on the web concerning this anymore.

Cool,

I just found the answer and it worked, i added this bit of code to my web.config and its now working fine.

 <pages
      validateRequest="false"
      pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
      pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
      userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

could somebody please tell me why i had to do this.

regards,
