problems upgrading MVC4 to MVC5

I'm trying to upgrade MVC4 to MVC5, but weird things happen. I used a pretty nice guide that I found and everything compiles OK, but when I try to show the website I get this error:

Could not load file or assembly 'System.Web.Helpers' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The weird thing is that when I look at the assembly references to System.Web.Mvc, System.Web.Razor, System.Web.WebPages, etc, they are all still at the version numbers that belong to MVC4! I've tried to reinstall the corresponding nuget packages, which gave me the sort of output you'd hope to get:

PM> Update-Package -reinstall -Id Microsoft.AspNet.Razor
Removing 'Microsoft.AspNet.Razor 3.2.3' from LabManager.Web.
Successfully removed 'Microsoft.AspNet.Razor 3.2.3' from LabManager.Web.
Uninstalling 'Microsoft.AspNet.Razor 3.2.3'.

Installing 'Microsoft.AspNet.Razor 3.2.3'.
You are downloading Microsoft.AspNet.Razor from Microsoft, the license agreement to which is available at http://www.microsoft.com/web/webpi/eula/net_library_eula_ENU.htm. Check the package for additional dependencies, which may come with their own license agreement(s). Your use of the package and dependencies constitutes your acceptance of their license agreements. If you do not accept the license agreement(s), then delete the relevant components from your device.

Successfully installed 'Microsoft.AspNet.Razor 3.2.3'.
Adding 'Microsoft.AspNet.Razor 3.2.3' to LabManager.Web.
Successfully added 'Microsoft.AspNet.Razor 3.2.3' to LabManager.Web.

which suggests that the correct versions have been installed. However, still the System.Web.Razor reference shows that it is at version 2.0.0.0. Also, I am compiling for .NET version 4.5.1, but the Runtime version of System.Web.Razor still shows 4.0.3.0319. The same goes for all the MVC related assemblies (except that the version number for System.Web.Mvc is 4.0.0.0 instead of 5.x.x.x).

Help! Does anyone have a clue what is going on here?

Edit: Here is my Web.Config:

It turns out that the referenced assemblies where not the ones installed by the mvc5 nuget packages, but by a bunch of old ones in a folder called '_bin_deployableAssemblies'. I simply removed that folder and visual studio figured out itself where to get the new ones. The version numbers of the MVC related assemblies appear correctly now and the application runs like charm.

You have problems with your binding redirects, they should be as follows:

    <dependentAssembly>
      <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
    </dependentAssembly>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>

In your current set up Helpers and WebPages point to version 2, Mvc points to version 4.

You will also need to check all of your view web.config's too, to makes sure they are also using the correct versions.

I used this guide to update my applications:

How to Upgrade an ASP.NET MVC 4 and Web API Project to ASP.NET MVC 5 and Web API 2
