Question

In my ASP.Net MVC application I have implemented a Custom ActionFilter to Authorize users.

I use CastleWindsor to provide dependency injection into all of the controllers as follows:

  protected virtual IWindsorContainer InitializeServiceLocator()
    {
        IWindsorContainer container = new WindsorContainer();
        ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));

        container.RegisterControllers(typeof(HomeController).Assembly);
        ComponentRegistrar.AddComponentsTo(container);

        ServiceLocator.SetLocatorProvider(() => new WindsorServiceLocator(container));

        return container;
    }

Within my CustomAttribute, I need a dependency that is used by all of my controllers, however I am unable to user Constructor based injection in an attribute.

So what’s the cleanest way out here? How can I provide the dependency?

Answer 1

OK – this seems to be a duplicate of Database injection into a validation attribute with ASP MVC and Castle Windsor which has been answered.

Also How do I use Windsor to inject dependencies into ActionFilterAttributes.

Having read through the above, and the referenced articles – the key one for me is http://weblogs.asp.net/psteele/archive/2009/11/04/using-windsor-to-inject-dependencies-into-asp-net-mvc-actionfilters.aspx for anyone else who is interested.
