Stuck Working Through Steven Sanderson's "ASP.NET MVC 2..."

I received a brief introduction to ASP.NET MVC in school and I am trying to expand that knowledge base with Steven Sanderson's book Pro ASP.NET MVC 2 Framework. It's been a great help, but I have hit a wall in the example that implements Ninject. I believe the DI is setup correctly, but when I try to specify the bindings for a dependency in my Ninject controller class, I receive one of two brown screens of death:

No parameterless constructor defined for this object.

Stack Trace:

Here is my code in the Ninject controller class:

public class NinjectControllerFactory : DefaultControllerFactory
{
    // A Ninject "kernel" is the things that can supply object instances
    private IKernel kernel = new StandardKernel(new SportsStoreServices());

    // ASP.NET MVC calls this to get the controller for each request
    protected override IController GetControllerInstance(RequestContext context, Type controllerType)
    {
        if (controllerType == null)
            return null;
        return (IController)kernel.Get(controllerType);
    }

    // Configures how abstract service types are mapped to concrete implementations
    private class SportsStoreServices : NinjectModule
    {
        public override void Load()
        {
            Bind<IProductsRepository>()
                .To<SqlProductsRepository>()
                .WithConstructorArgument("connectionString",
                    ConfigurationManager.ConnectionStrings["AppDb"].ConnectionString
                    );
        }
    }
}

The book is pushing up against the limits of my understanding, but I am following along and have been able to debug everything up to this point. This has me stumped. Any idea where I would begin to debug this?

Both issues are related to Ninject not being setup or integrated correctly. The trunk version of Ninject allows you to bypass having to define custom controller factories. It's a cleaner setup and less confusing.

See:

• http://codeclimber.net.nz/archive/2009/08/14/how-to-use-ninject-2-with-asp.net-mvc.aspx

Additionally you should check out the article listed here

• Ninject and Custom Controller Factory

Did you update your application_start in global.asax to point to the ninject controller factory?

as such:

protected void Application_Start() {
..........

  ControllerBuilder.Current.SetControllerFactory(new NinjectControllerFactory ());
}
