R – Castle Windsor Fluent Registration – What does Pick() do

apicastle-windsorfluent-interface

When using auto-registration with castle windsor I see people doing things like 

_container.Register(
  AllTypes.Pick().FromAssembly(Assembly.GetExecutingAssembly())
    .WithService.FirstInterface());

For the life of me I can't figure out what the Pick() method does nor can I find any documentation. Can anyone explain it to me?

Pick(IEnumerable<Type>) is a synonym for From(IEnumerable<Type>), i.e. it selects the specified types as registration targets.

AllTypes.Pick() is the same as AllTypes.Of<object>(), so it effectively selects all types.

AllTypes.Pick().FromAssembly(Assembly.GetExecutingAssembly()) will select ALL types in the executing assembly (you can then filter, of course)

As usual, take a look at the fluent API wiki and/or test case for more information.
