Ninject ActivationException - ninject

Question

I'm getting the infamous "Error activating XYZ. No matching bindings are available blah blah blah" from Ninject 3.0.1.10 in an ASP.NET MVC project.
The following is how I've setup my binding (very simple):
public static class NinjectWebCommon
{
private static readonly Bootstrapper bootstrapper = new Bootstrapper();
/// <summary>
/// Starts the application
/// </summary>
public static void Start()
{
DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
bootstrapper.Initialize(CreateKernel);
}
/// <summary>
/// Stops the application.
/// </summary>
public static void Stop()
{
bootstrapper.ShutDown();
}
/// <summary>
/// Creates the kernel that will manage your application.
/// </summary>
/// <returns>The created kernel.</returns>
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
RegisterServices(kernel);
return kernel;
}
private static void RegisterServices(IKernel kernel)
{
string connectionString = WebConfigurationManager.ConnectionStrings["STAGING"].ConnectionString;
kernel.Bind<IUserAccountRepository>()
.To<SqlUserAccountRepository>()
.WithConstructorArgument("connectionString", connectionString);
kernel.Bind<IRecipeRepository>()
.To<SqlRecipeRepository>()
.WithConstructorArgument("connectionString", connectionString);
kernel.Bind<HomeViewModel>().ToSelf();
}
}
When the controller Index action is invoked it attempts to create a HomeViewModel object as such:
public ActionResult Index()
{
IKernel kernel = new StandardKernel();
HomeViewModel model = kernel.Get<HomeViewModel>();
...
Which triggers the exception:
Error activating IRecipeRepository No matching bindings are available, and the type is not self-bindable.
Activation path:
2) Injection of dependency IRecipeRepository into parameter recipeRepository of constructor of type HomeViewModel
1) Request for HomeViewModel
But if I attempt to get an instance of HomeViewModel directly after calling kernel.Bind in RegisterServices then it works fine.
Here's what the HomeViewModel looks like (some details removed for sake of brevity):
public class HomeViewModel
{
public HomeViewModel(IRecipeRepository recipeRepository,
IUserAccountRepository userAccountRepository)
{
this.recipeRepository = recipeRepository;
this.userAccountRepository = userAccountRepository;
}
//
// Some details removed for sake of brevity
//
private readonly IRecipeRepository recipeRepository;
private readonly IUserAccountRepository userAccountRepository;
}
Any idea what I'm missing? Why is the controller "special" in this case?
