I have done a similar thing with Castle.

You can create a new class that inherits from MvcApplication and then change your global.asax file to point to this new class. So your new class will look something like this:

public class YourUmbracoWebApplication : MvcApplication {

        protected override void Application_Start() 

        {

            // Do your IoC initialisation here...

            base.Application_Start();

        }

    }

And your Global.asax will look like this:

 <%@ Application Codebehind="Global.asax.cs" Inherits="YourUmbracoWebApplication" Language="C#" %>

Hope this helps :)

Right, that's simple enough. However I still need to initialize the container properly, so that Umbraco can use Ninjecvt instead of Autofac - how do I go about that?

I have never used Ninject so I cannot really provide code samples for it.

Using Castle you'd initialize your container and register your types (I am assuming Ninject is not too dissimilar). So the Application_Start (using a very crude example) would look like this:

protected void Application_Start
{
  IWindsorContainer = new WindsorContainer();
  container.Register(
    Component.For<IYourService>().ImplementedBy<YourConcreteService>().LifeStyle.Singleton
  );
}

That's absolutely correct. 

Is there a list of types that needs to be registered for Umbraco to run?

Is there some kind of a adapter to the container ? For instance Umbraco might wish to resolve a named instance of a given type etc.

I have just re-read your first post and you are actually looking to completely replace AutoFaq with Ninject not just control your own custom objects with a different IoC container, sorry I should have read it more carefully.

Having a look at the Umbraco 5 source it appears that the DI has been abstracted and there is a IContainerBuilder interface in Umbraco.Framework.DependencyManagement that is implemented in a seperate AutoFac library (Umbraco.Framework.DependencyManagement.Autofac).

I'd probably start with the source from this library and adapt it to use Ninject (sorry that's a really obvious statement!).

I'll have a look at it later tonight, and get back to the topic ;) Cheers for the hints.

I am curious as to how easily you'll be able to do this :)
