I have an MVC solution that was 3.0.0.0 but I'm upgrading it to 4.0.0.1. I've upgraded the System.Web.Mvc reference (in the reference folder) and it's dependencies, e.g. updated System.Web.WebPages from 1 to 2.
When I build the project it builds without issue, however when I run the project I get the following error:
Compiler Error Message: CS1705: Assembly 'MobileScanner, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'System.Web.Mvc, Version=4.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'System.Web.Mvc, Version=3.0.0.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
P.S. Using VS2010, and .Net 4.0
MobileScanner
uses MVC 4.0 and your references version still shows version 3.0 , Did you update your system mvc dll as well? – Rajshekar Reddy
