I'm trying to use Windsor as a factory to provide specification implementations based on subtypes of XAbstractBase
(an abstract message base class in my case).
I have code like the following:
public abstract class XAbstractBase { }
public class YImplementation : XAbstractBase { }
public class ZImplementation : XAbstractBase { }
public interface ISpecification<T> where T : XAbstractBase
{
bool PredicateLogic();
}
public class DefaultSpecificationImplementation : ISpecification<XAbstractBase>
{
public bool PredicateLogic() { return true; }
}
public class SpecificSpecificationImplementation : ISpecification<YImplementation>
{
public bool PredicateLogic() { /*do real work*/ }
}
My component registration code looks like this:
container.Register(
AllTypes.FromAssembly(Assembly.GetExecutingAssembly())
.BasedOn(typeof(ISpecification<>))
.WithService.FirstInterface()
)
This works fine when I try to resolve ISpecification<YImplementation>
; it correctly resolves SpecificSpecificationImplementation
.
However, when I try to resolve ISpecification<ZImplementation>
Windsor throws an exception:
"No component for supporting the service ISpecification'1[ZImplementation, AssemblyInfo...] was found"
Does Windsor support resolving generic implementations down to base classes if no more specific implementation is registered?
