Castle Windsor Fluent Registration Problem

Question

Hello everybody,

I do have the following class: public class MainView : IHandle<MessageOne>,
IHandle<MessageTwo>...

I would like to register all classes implementing at least one closed version of the IHandle<> Interface with the fluent registration of Castle Windsor but it does not work. BasedOn(typeof(IHandleThe<>)) is not selecting the right types. I use the following statement:

container.Register(AllTypes
                     .FromAssemblyNamed("MyAssembly")
                   //.If(t => t.Name.EndsWith("View")
                     .BasedOn(typeof(IHandleThe<>))
                     .Configure(registration => DoStuff())
                     .WithService.Base);

The above code does not get into the Configure call but when I comment the BasedOn line and uncomment the If line, then it works. The If is not too helpful, though. Does anybody have an idea what I am doing wrong.

Any ideas/help is appreciated

Best regards Gope

That's one of less intuitive things about the API. If you take a look at the documentation, you'll find that Pick BasedOn and Where do xor, so the code above would register two sets of types:

1. Types that have name ending with "View" (with default connfiguration, that is as themseles)

2. Types that are based on IHandleThe<> (all of them found in the assembly, the previous condition does not apply here) and configure them to the base service, and whatever the DoStuff method does.

To achieve what you want (based on the type AND if name ends with If) the BasedOn call must go first, all the other ones must go after it.
