Create a null implementation of IBar that NOPs all methods. That way MyService doesn't have a dangling null reference that will likely cause problems in the code. In your new project register the null implementation with windsor, everywhere else register the concrete implementation.
From: [email protected] [mailto:[email protected]] On Behalf Of Scott_M Sent: 25 July 2012 22:13 To: [email protected] Subject: Windsor / null dependency injection Ran into a recent case where one of my new apps is using a component where a constructor based dependency of that component is not necessary (IBar) and would be painful to inject (lot of projects/related projects to import/build). Here is a simplified example: public MyService : IService { private IFoo _foo; private IBar _bar; public MyService(IFoo foo, IBar bar) { _foo = foo; _bar = bar; } } So lets say that the IBar dependency is not needed for the current application but IFoo is. Is there a good way to inject NULL for that dependency using windsor config / XML / Nullable<T>? How is this done? thanks -- You received this message because you are subscribed to the Google Groups "Castle Project Users" group.
