I'm trying to use the new ASP.Net MVC 4 Web API project template with Ninject but have hit a wall on the following error:
Method 'GetFilters' in type 'Ninject.Web.WebApi.Filter.DefaultFilterProvider' from assembly 'Ninject.Web.WebApi, Version=3.0.0.0, Culture=neutral, PublicKeyToken=c7192dc5380945e7' does not have an implementation.
I am creating a brand new project in Visual Studio 2010 using the ASP.Net MVC 4 -> Web API template and I am using the latest Ninject NuGet packages:
I have attempted the solution presented in this question however I've not had any luck - if I remove the reference to Ninject.Web.WebApi then MVC never engages Ninject. I also notice they mention Ninject.MVC3 however I am using the new Ninject.WebApi plugin.
I am using the default binding code in NinjectWebCommon.cs that is created during the NuGet install and attempting to register one simple service in RegisterServices()
[assembly: WebActivator.PreApplicationStartMethod(typeof(mkts.web.App_Start.NinjectWebCommon), "Start")]
[assembly: WebActivator.ApplicationShutdownMethodAttribute(typeof(mkts.web.App_Start.NinjectWebCommon), "Stop")]
namespace mkts.web.App_Start
{
using System;
using System.Web;
using Microsoft.Web.Infrastructure.DynamicModuleHelper;
using Ninject;
using Ninject.Web.Common;
using mkts.service;
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;
}
/// <summary>
/// Load your modules or register your services here!
/// </summary>
/// <param name="kernel">The kernel.</param>
private static void RegisterServices(IKernel kernel)
{
//Test binding
kernel.Bind<IStudentService>().To<StudentService>();
}
}
}
My controller:
namespace mkts.web.Controllers
{
public class HomeController : Controller
{
private readonly IStudentService studentService;
public HomeController(IStudentService studentService)
{
this.studentService = studentService;
}
public ActionResult Index()
{
return View();
}
}
}
Many thanks in advance for any help with this.
Ninject.WebApi was written against the Beta and is deprecated now.
Remove that, install Ninject.MVC3.
Now you will need a homebrewed IDependencyResolver and IDependencyScope. I posted a walkthrough here - http://www.strathweb.com/2012/05/using-ninject-with-the-latest-asp-net-web-api-source/
