NinjectDependencyResolver fails binding ModelValidatorProvider

Question

I\'m developing an ASP.NET Web Api 2.2 with C#, .NET Framework 4.5.1.

After updating my Web.Api to Ninject 3.2.0 I get this error:

Error activating M

Be sure that any old Ninject or Ninject.Web.Common.* dlls aren't present in your bin folder.

I had the same issue in my solution after I had uninstalled Ninject.Web.Common, Ninject.Web.Common.WebHost, Ninject.Web.WebApi, and Ninject.MVC5 from Nuget and installed WebApiContrib.IoC.Ninject in order to use GlobalConfiguration.Configuration.DependencyResolver as in your example. I kept the version of Ninject that I already had installed (which was indeed 3.2.2).

The error did not appear when I first made my changes. However, after moving around from a few git branches and back to my current work, I saw the error. The code that had run fine last week was now throwing the same exact error.

It seems that my bin folder had references to the old Ninject.* packages I had removed. Upon deleting those files, my project worked as expected.
