  • 0

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 during 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.

    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">
