Using Ninject with Asp.NET Web API Beta ApiController

Question

I'm stuck. I was using the method outlined here for wcf web api p6 Ninject working with WCF Web API Preview 5, however things are quite a bit different with the mvc implementation in the beta. There is a good article here http://www.asp.net/web-api/overview/extensibility/using-the-web-api-dependency-resolver that talks about building your own custom dependency resolver, however i would like to use the same implementation i'm using for my mvc view controllers...e.g. Ninject. I've tried a few things based on the IoC Unity example in the article too, but nothing has panned out yet. Any help pointing me in the right direction would be much appreciated. I'm going to keep digging on my own as well. Thanks in advance!

Here's where I'm at. I was using WebActivator to bootstrap the code but I've since dropped it to the Application_Start() just to take one more thing out of the equation.

    protected void Application_Start()
    {
        var kernel = new StandardKernel(new MyNinjectModule());
        GlobalConfiguration.Configuration.ServiceResolver.SetResolver(new NinjectDependencyResolver(kernel));
    }

And am receiving the following error:
The type Ninject.Web.Mvc.NinjectDependencyResolver does not appear to implement Microsoft.Practices.ServiceLocation.IServiceLocator.
Parameter name: commonServiceLocator

Found the solution
Perhaps there is/will be a more elegant way but this is now working for me. I'm also adding my custom message handler here as well.

[assembly: WebActivator.PreApplicationStartMethod(typeof(MyApp.AppStart.ApiBootstrapper), "Start")]
namespace MyApp.AppStart
{
    public class ApiBootstrapper
    {
        public static void Start()
        {
            var kernel = new StandardKernel(new MyNinjectModule());
            var resolver = new NinjectDependencyResolver(kernel);
            GlobalConfiguration.Configuration.ServiceResolver.SetResolver(resolver.GetService, resolver.GetServices);
            GlobalConfiguration.Configuration.MessageHandlers.Add(new ApiAuthHandler());
        }
    }
}

Answer 1

I never used the WebAPI but since the semantic of the IDependencyResolver is exactly the same as the one from MVC3 you should be able to use the same implementation: https://github.com/ninject/ninject.web.mvc/blob/master/mvc3/src/Ninject.Web.Mvc/NinjectDependencyResolver.cs

Update: The Ninject.Web.WebAPi extension adds support for ApiControllers

I found the answer and updated my question above with the solution. The solution itself was more or less present in the Using the Web API Dependency Resolver article, i just had to keep tweaking for ninject. Both answers helped me quickly narrow this down so thanks to @Remo and @James.
