Strange MVC Referencing Issue

votes

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

Do you have multiple projects? If so, did you upgrade MVC in all of them that reference it? - krillgar
Do you have the right versions in package.config? - Alexander Derck
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
Somewhere you still have MVC v3. Find it and update it. Application CheckAsm is useful for this. - trailmax
check the version of the mvc dll here `C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies` - Rajshekar Reddy

Thanks for your help but I fixed it.

The issue was that there were still references to MVC 3 and some of it's (old) dependencies (System.Web.Razor) in the root web.config and then again in the Views/web.config... once updated it worked a treat.
