In order to ease the pains of registering types to an IoC container, we include a DefaultConventionInstaller which registers components automatically to the IoC container based on naming conventions. The class Foo will be automatically registered to interface IFoo, provided of course that it implements IFoo. This is accomplished using Windsor’s registration conventions which are documented here. By default we register all components with a Lifestyle of PerWebRequest, so one instance will be created per web request. If you need to register a component with a different lifestyle than this, you will also need to exclude it from the default convention. You can see an example of this below, where we exclude anything that is an IController because they are registered with a Transient Lifestyle in another installer

public void Install(IWindsorContainer container, IConfigurationStore store)
{
    container.Register(
        Classes.FromThisAssembly().Pick()
            .WithServiceDefaultInterfaces()
            .Unless(type => typeof(IController).IsAssignableFrom(type))
            .LifestylePerWebRequest()
        );
}
