Question

I upgraded my MVC3 project to MVC4 without much trouble but the Web API (the reason why I did it) is not working because, apparently, there’s something referencing NHibernate.

<Exception>
  <ExceptionType>System.IO.FileNotFoundException</ExceptionType>
  <Message>Could not load file or assembly 'NHibernate, Version=3.1.0.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4' or one of its dependencies. The system cannot find the file specified.</Message>

I removed the references to NHibernate because I tried adding FunnelWeb blog to my site but I ended up with two completely different practices in the same project and I didn’t like that at all.

And I don’t think it’s a good idea to put the NHibernate library in place again because I would hiding something I should know about.

I have tried NDepend but in no way NHibernate was found.

Note that my project is compiling and running fine. Any ideas please?

Have you tried erasing your bin directory?
