answer:

you will get a smiler exception if you have

Created a project using mvc 1.0 and then removed the reference  mvc 1 and added mvc 2 or greater

visual studio does not automatically update web.config file and in some cases the project file csprj or vbprj file to update the version of mvc you are using so you will have to do it manually

in web.config file update the version  from the line

<add assembly=”System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35″/>

TO
<add assembly=”System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35″/>

other sections of web.config  like

<add verb=”*” path=”*.mvc” validate=”false” type=”System.Web.Mvc.MvcHttpHandler, System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35″/>

<add name=”MvcHttpHandler” preCondition=”integratedMode” verb=”*” path=”*.mvc” type=”System.Web.Mvc.MvcHttpHandler, System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35″/>
