Castle Windsor: Auto-register types from one assembly that implement interfaces from another

I use Castle Windsor as my IoC container. I have an application that has a structure similar to the following:

• MyApp.Services.dll
  • IEmployeeService
  • IContractHoursService
  • ...
• MyApp.ServicesImpl.dll
  • EmployeeService : MyApp.Services.IEmployeeService
  • ContractHoursService : MyApp.Services.IContractHoursService
  • ...

I use the XML configuration at the moment, and every time I add a new IService/Service pair, I have to add a new component to the XML configuration file. I want to switch all this over to the fluent registration API but haven't worked out exactly the right recipe to do what I want yet.

Can anyone help? The lifestyles will all be singleton.

Many thanks in advance.
