How to use Ninject bootstrapper in WebApi OwinHost Startup?

Question

I am migrating from IIS WebAPI to OwinHost. Utilizing the latest pre-release versions of nuget packages, I successfully used instructions here:

Add the following nuget-packages to your application:

1. Install-Package Microsoft.AspNet.WebApi.Owin
2. Install-Package Ninject

If you are using web api version 5.0.0.0 you also need to download the Ninject Resolver class from the repo to avoid compatability issues.

Create a static method that returns a Kernel object

public static class NinjectConfig
{
    public static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        //Create the bindings
        kernel.Bind().To();
        return kernel;
    }
}

Then you can use ninject in your startup class

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var config = new HttpConfiguration();
        config.DependencyResolver = new NinjectResolver(NinjectConfig.CreateKernel());

        config.Routes.MapHttpRoute("default", "api/{controller}/{id}", new { id=RouteParameter.Optional });

        app.UseWebApi(config);
    }
}
