I\'ve upgraded MVC3 from RC2 to RTM. We were using Ninject 2.1.0.76, but things stopped working once I upgraded. So I used the NuGet manager to get the latest Ninject, Ninject.M
Download the dlls from here

Further more do not use Ninject.MVC3 all you need ist Ninject.Web.Mvc
I also have an article documenting same here
