9.35 Lazy Component Loaders
The preferred way of registering components in Windsor is to do it upfront via Windsor Installers. Windsor exposes another way - registering the components on the spot, right when it's first requested. This feature is targeted mostly at integration with external frameworks - like WCF.
Lazy component loaders are types implementing ILazyComponentLoader interface. It exposes just single method:
IRegistration Load(string key, Type service)
Implementation should either return null which means it's not interested in loading the service, or service for given key and/or type.
Example
For example let's assume you have set up a convention that default implementation of your interfaces would be a class called DefaultinterfaceName living in the same namespace. So for an interface Acme.Services.IFoo the default implementation would be called Acme.Services.DefaultFoo. Now if you wanted to lazily register these implementation you could create a loader that could look something like the following:
