Ninject binding with generic repository MVC returns error on Parameterless Constructor

Question

I'm trying to use a fairly simple generic repository for a number of administration lists in an application. Functionality for the admin users is just CRUD to keep the lists up to date for use elsewhere as lookups.

I keep getting an error of the form:

An error occurred when trying to create a controller of type 'WhatWorks.Controllers.AchievementController'. Make sure that the controller has a parameterless public constructor.

I've read an awful lot of posts on SO and blogs found through Google but I can't find an answer (at least nothing that makes sense to me as an answer which may be another problem...)

My code is as follows:

Controller

public class AchievementController : BootstrapBaseController
{
    private readonly IAdminRepository<tAchievement> _repo;

    public AchievementController(IAdminRepository<tAchievement> _repo)
    {
        this._repo = _repo;
    }

ViewModel

public partial class AchievementListViewModel
{
    public int Id { get; set; }
    public string achievement { get; set; }
}

Interface

public interface IAdminRepository<TEntity> : IDisposable 
                    where TEntity : class                            
{
    IEnumerable<TEntity> Get();
    TEntity GetByID(int id);
    void Insert(TEntity entity);
    void Delete(TEntity entity);
    void Update(TEntity entity);
    void Save();
}

Repository

public class AdminRepository<T> : IAdminRepository<T>
                        where T : class
    {
        private WhatWorksEntities objContext;

        public AdminRepository()
        {
            objContext = new WhatWorksEntities();
        }

        public IEnumerable<T> Get()
        {
            return objContext.Set<T>().ToList();
        }

        etc.

Binding

kernel.Bind(typeof(IAdminRepository<>)).To(typeof(AdminRepository<>));

I've also tried binding with an additional line to no effect:

kernel.Bind<IAdminRepository<tAchievement>>().To<AdminRepository<tAchievement>>();

I'm assuming I'm missing something simple.

I have Ninject, Ninject.Web.MVC and Ninject.Web.Common in my references - all taken from NuGet.

Stack Trace is as follows:

_____________EDIT with partial answer_____________

Having recreated a project from scratch and hit the same error I noticed that the versions of a few of the additional packages I was using had changed. I'm using "Twitter Bootstrap for MVC" by Eric Hexter as my main display and this is pulling in a later version of Twitter Bootstrap than I've used previously. I'm not sure if this is causing the problem but the layout of the folders in an older working project are different from the new one.

This answer has given me a decent pointer after the comments by Trevor Pilley: Ninject + MVC3 is not injecting into controller

In my older working project the following was in the Web.config file but is not in the new project. If I add it, the code works but there is still a problem with the Twitter Bootstrap layout - probably from the new .css files - I'll leave the question open for in case anyone can improve on this as an answer.

(Entity Framework closing tag left in to show location in Web.config)

_________EDIT global.asax______________________

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BootstrapSupport.BootstrapBundleConfig.RegisterBundles(System.Web.Optimization.BundleTable.Bundles);
        WhatWorksRouteConfig.RegisterRoutes(RouteTable.Routes);
        AutoMapperConfiguration.Configure();
    }
}

You need to tell the MVC runtime to use Ninject to resolve your controllers, the easiest way to do this is install the MVC extension for Ninject
