WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

Installing MVC directly on your web server is one option, as then the assemblies will be installed in the GAC. You can also bin deploy the assemblies, which might help keep your server clear of pre-release assemblies until a final release is available.

Phil Haack posted a nice article a couple days ago about how to deploy MVC along with your app, so it's not necessary to install directly:

I am using Jenkins with .net projects and had troubles with MVC 4 references.

I finallys solved my issue by using a .Net reference search engine functionality based on the registry using :

"HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NETFramework\v2.0.50727\AssemblyFoldersEx"

You can create subkey et set the default key to "c:\myreferenceedir" for example.

It saved me with MVC versions and also ASP.net Web pages.

Usefull to add references to the "Add Reference Dialog"
