Custom providers

Providers are specialized factory classes that Ninject uses in order to instantiate resolved types. Whenever we bind a service type to a component, we are implicitly associating that service type to a provider that can generate instances of that component. This hidden provider is a generic factory, which can create instances of every given type, and is called StandardProvider.
