I have been wrapping my head around this and thus far existing questions and answers did not help. So I will try it as well. I am trying to hook up Ninject in Umbraco. What do I have so far:

A class called NinjectWebCommon. This Class was created by NuGet when installing Ninject.

In this class I have added register service like Ninject and NLog document:

        private static void RegisterServices(IKernel kernel)
        {
            kernel.Bind<ILogger>().To<NLogger>().InSingletonScope();
        }

    [Application("MyApp", "MyApp", "app.gif", 8)]
    public class StartupHandler: IApplicationEventHandler

DependencyResolver.Current.GetService<ILogger>().LogInfo("Application Started");

Also when I call an action on my controller that has the iLogger injected I receive an error that there is no parameterless constructor. But if I do that my dependency is never injected.

Any thought, starting points, etc for using IoC in Umbraco 6
