Ninject dependency for Ninject.Web.WebApi.OwinHost v3.2.x

I'm attempting to ninject ApiControllers in an Azure worker role. I've previously accomplished ninjection with the same controllers in an asp.net mvc 5 / web api 2 project in the same solution. Another non ninjected test controller in this WorkerRole project work and serve expected results.

While attempting to add the NuGet package Ninject.Web.WebApi.OwinHost (version 3.2.x) it looks like that package is ?erroneously? requiring a Ninject version ≥ 3.0.0.0 && < 3.1.0.0

I've tried 

Install-Package Ninject.Web.WebApi.OwinHost -ProjectName WorkerRole1
Install-Package Ninject.Web.WebApi.OwinHost -Pre -ProjectName WorkerRole1
Install-Package Ninject.Web.WebApi.OwinHost -Version 3.2.0 -ProjectName WorkerRole1
Install-Package Ninject.Web.WebApi.OwinHost -Version 3.2.1-unstable-002 -ProjectName WorkerRole1

I was able to successfully add Ninject.Web.WebApi.SelfHost, however I believe I need the owin flavor and SelfHost didn't appear to install NinjectWebCommon.cs or equivalent. I don't know where to wire up ninject to the owin self host in the worker role once I am successful at including the OwinHost. I'm assuming it will be scaffold-ed in.

Result of attempting to install Ninject.Web.WebApi.OwinHost

Probably unrelated however in checking versions of installed package in the WorkerRole I note that a number of packages are IIS specific. Are these needed in an Azure WorkerRole Owin self host? And specifically for Microsoft.AspNet.WebApi.SelfHost I see the following notation yet I do have Microsoft.AspNet.WebApi.OwinSelfHost installed.

This is a legacy package for hosting ASP.NET Web API within your own process (outside of IIS). Please use the Microsoft.AspNet.WebApi.OwinSelfHost package for new projects.

I know this is late, but I ran into this same problem and found this question via a Google search. I eventually got around it with -DependencyVersion:

Install-Package Ninject.Web.WebApi.OwinHost -DependencyVersion Highest

If you don't want to update all of the dependent NuGet packages, I found that manually installing all of the Ninject-related dependencies for Ninject.Web.WebApi.OwinHost and then installing Ninject.Web.WebApi.OwinHost also got around the issue.

This allowed the Install-Package to succeed. Haven't had any success finding documentation for the "-DependencyVersion Highest" in the nuGet docs. Was hoping one of the Ninject authors or maintainers might comment. – Joscelin

I was facing the same problem today and I solved it by the following add the following class implementation to your project

    public class NinjectDependencyScope : IDependencyScope
        {
            IResolutionRoot resolver;

            public NinjectDependencyScope(IResolutionRoot resolver)
            {
                this.resolver = resolver;
            }

            public object GetService(Type serviceType)
            {
                if (resolver == null)
                    throw new ObjectDisposedException("this", "This scope has been disposed");

                return resolver.TryGet(serviceType);
            }

            public System.Collections.Generic.IEnumerable<object> GetServices(Type serviceType)
            {
                if (resolver == null)
                    throw new ObjectDisposedException("this", "This scope has been disposed");

                return resolver.GetAll(serviceType);
            }

            public void Dispose()
            {
                IDisposable disposable = resolver as IDisposable;
                if (disposable != null)
                    disposable.Dispose();

                resolver = null;
            }
        }

    // This class is the resolver, but it is also the global scope
    // so we derive from NinjectScope.

public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
{
    IKernel kernel;

    public NinjectDependencyResolver(IKernel kernel)
        : base(kernel)
    {
        this.kernel = kernel;
    }

    public IDependencyScope BeginScope()
    {
        return new NinjectDependencyScope(kernel.BeginBlock());
    }
}

2- then in NinjectWebCommon

add the following line of code to this method CreateKernel(): GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel); so the complete implementation will be:

private static IKernel CreateKernel()
        {
           var kernel = new StandardKernel();
            try
            {
                kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
                kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
                // Install our Ninject-based IDependencyResolver into the Web API config
                GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);

                RegisterServices(kernel);
                return kernel;
            }
            catch
            {
                kernel.Dispose();
                throw;
            }
        }

I tried this code my self and it works successfully
