Question

When I use this registration:

container.Register(
    Component
        .For<IFooFactory>()
        .ImplementedBy<FooFactory>(),
    Component
        .For<IFoo>()
        .UsingFactoryMethod(kernel => kernel.Resolve<IFooFactory>().CreateFoo())
);

I get this exception:

Castle.MicroKernel.ComponentRegistrationException: Type MyNamespace.IFoo is abstract. As such, it is not possible to instansiate it as implementation of MyNamespace.IFoo service

I m not really sure what the problem is. But the stack trace shows that in DefaultComponentActivator.CreateInstance() , the following condition succeeds and then the error is thrown:

if (createProxy == false && Model.Implementation.IsAbstract)

Do I need a proxy of some sort here? Is the registration wrong?

Answer 1

From the message it seems you haven t registered the IFooFactory.

Also You need to add support for the factory method. Just call this before you doing the registration:

container.AddFacility<Castle.Facilities.FactorySupport.FactorySupportFacility>();
