Ninject + "Error loading Ninject ICache component"

Question

I just installed the new Ninject.MVC3 from NuGet and tried to get it working in my asp.net mvc 3 application, however I am getting this strange error now and then when surfing on my website:

[InvalidOperationException: Error loading Ninject component ICache No such component has been registered in the kernel component container. Suggestions: 1) If you have created a custom subclass for KernelBase, ensure that you have properly implemented the AddComponents() method. 2) Ensure that you have not removed the component from the container via a call to RemoveAll(). 3) Ensure you have not accidentally created more than one kernel. ] Ninject.Components.ComponentContainer.Get(Type component) in d:\BuildAgent-01\work\b68efe9aafe8875e\src\Ninject\Components\ComponentContainer.cs:146 Ninject.Components.ComponentContainer.Get() in d:\BuildAgent-01\work\b68efe9aafe8875e\src\Ninject\Components\ComponentContainer.cs:102 Ninject.KernelBase.CreateContext(IRequest request, IBinding binding) in d:\BuildAgent-01\work\b68efe9aafe8875e\src\Ninject\KernelBase.cs:540 Ninject.<>c__DisplayClassa.<Resolve>b__6(IBinding binding) in d:\BuildAgent-01\work\b68efe9aafe8875e\src\Ninject\KernelBase.cs:375 System.Linq.<>c__DisplayClass12`3.<CombineSelectors>b__11(TSource x) +20 System.Linq.WhereSelectEnumerableIterator`2.MoveNext() +151 System.Linq.Enumerable.SingleOrDefault(IEnumerable`1 source) +4178557 Ninject.Web.Mvc.NinjectDependencyResolver.GetService(Type serviceType) in c:\Projects\Ninject\ninject.web.mvc\mvc3\src\Ninject.Web.Mvc\NinjectDependencyResolver.cs:56 System.Web.Mvc.DefaultControllerActivator.Create(RequestContext requestContext, Type controllerType) +51 [InvalidOperationException: An error occurred when trying to create a controller of type 'MyApp.Controllers.NewsController'.

And my code is:

//AppStart_NinjectMVC3.cs

  using System.Web.Mvc; using Ninject.Modules; [assembly: WebActivator.PreApplicationStartMethod(typeof(MyApp.AppStart_NinjectMVC3), "Start")] namespace MyApp { using Microsoft.Web.Infrastructure.DynamicModuleHelper; using Ninject; public static class AppStart_NinjectMVC3 { public static void Start() { DynamicModuleUtility.RegisterModule(typeof(OnePerRequestModule)); DynamicModuleUtility.RegisterModule(typeof(NinjectHttpApplicationModule)); } } } 

//NinjectHttpApplicationModule.cs

 using MyApp.Data; using NHibernate; namespace MyApp { using System; using System.Web; using Ninject; using Ninject.Web.Mvc; public sealed class NinjectHttpApplicationModule : IHttpModule, IDisposable { #region Ninject Mvc3 extension bootstrapper (Do not touch this code) private static readonly Bootstrapper bootstrapper = new Bootstrapper(); private static bool initialized; private static bool kernelDisposed; /// <summary> /// Initializes a module and prepares it to handle requests. /// Do not change this method! /// </summary> /// <param name="context">An <see cref="T:System.Web.HttpApplication"/> that provides access to the methods, properties, and events common to all application objects within an ASP.NET application</param> public void Init(HttpApplication context) { lock (bootstrapper) { if (initialized) { return; } initialized = true; bootstrapper.Initialize(CreateKernel); } } /// <summary> /// Disposes the <see cref="T:System.Web.HttpApplication"/> instance. /// Do not change this method! /// </summary> public void Dispose() { lock (bootstrapper) { if (kernelDisposed) { return; } kernelDisposed = true; bootstrapper.ShutDown(); } } #endregion /// <summary> /// Creates the kernel that will manage your application. /// </summary> /// <returns>The created kernel.</returns> private static IKernel CreateKernel() { var kernel = new StandardKernel(); RegisterServices(kernel); return kernel; } /// <summary> /// Load your modules or register your services here! /// </summary> /// <param name="kernel">The kernel.</param> private static void RegisterServices(IKernel kernel) { kernel.Bind<ISession>().ToMethod(x => kernel.Get<SessionFactoryBuilder>().CreateFactory().OpenSession()).InRequestScope(); kernel.Bind<ITransaction>().ToMethod(x => kernel.Get<ISession>().BeginTransaction()).InRequestScope(); kernel.Bind(typeof(IRepositoryBase<>)).To(typeof(RepositoryBase<>)); kernel.Bind<IUnitOfWork>().To<UnitOfWork>(); } } } 

Most of the code is used by default when installing NuGet .. The only thing I did was add bindings to RegisterServices()

Any suggestions?

Answer 1

Fixed in 2.2.1.0

See http://www.planetgeek.ch/2011/03/01/ninject-2-2-1-0-and-ninject-mvc3-2-2-1-0-released/ for more details.

Answer 2

Looks like his error is consistent with this thread and that they are working on a fix ...

Answer 3

As mentioned earlier, this seems like an error.
One option is to simply implement the Singleton extension method:

 public static class NinjectSingletonExtension { public static CustomSingletonKernelModel<T> SingletonBind<T>(this IKernel i_KernelInstance) { return new CustomSingletonKernelModel<T>(i_KernelInstance); } } public class CustomSingletonKernelModel<T> { private const string k_ConstantInjectionName = "Implementation"; private readonly IKernel _kernel; private static object padlock = new Object(); private T _concreteInstance; public CustomSingletonKernelModel(IKernel i_KernelInstance) { this._kernel = i_KernelInstance; } public IBindingInNamedWithOrOnSyntax<T> To<TImplement>(TImplement i_Constant = null) where TImplement : class, T { _kernel.Bind<T>().To<TImplement>().Named(k_ConstantInjectionName); var toReturn = _kernel.Bind<T>().ToMethod(x => { if (i_Constant != null) { return i_Constant; } if (_concreteInstance == null) { lock (padlock) { if (_concreteInstance == null) { _concreteInstance = _kernel.Get<T>(k_ConstantInjectionName); } } } return _concreteInstance; }).When(x => true); return toReturn; } } 

And then just use:

 i_Kernel.SingletonBind<T>().To<TImplement>(); 

Instead of this

 i_Kernel.Bind<T>().To<TImplement>().InSingletonScope();
