ActivationException при использовании ToFactory в Ninject

Question

Когда я пытаюсь использовать ToFactory в Ninject, я получаю Ninject.ActivationException

var test = new StandardKernel(); 
test.Bind<IFoo>().To<Foo>(); 
test.Bind<IFooFactory>().ToFactory(); 
var factory = test.Get<IFooFactory>(); 
var foo = factory.GetFoo();   //<--Ninject.ActivationException 

завод:

public interface IFooFactory 
{ 
    IFoo GetFoo(); 
} 

Исключение:

Ninject.ActivationException was unhandled 
    Message=Error activating IFoo 
No matching bindings are available, and the type is not self-bindable. 
Activation path: 
    1) Request for IFoo 

Suggestions: 
    1) Ensure that you have defined a binding for IFoo. 
    2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. 
    3) Ensure you have not accidentally created more than one kernel. 
    4) If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name. 
    5) If you are using automatic module loading, ensure the search path and filters are correct.

Answer 1

naming of your method is triggering a convention such that the resulting generated factory is requesting an IFoo named "Foo", но конфигурация не зарегистрировала услугу этого типа под этим именем.
