Via Windsor I register multiple implementation types to a single interface type :
public class WindsorInstaller : IWindsorInstaller
{
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.Register(
Component.For<IMyType>()
.ImplementedBy<MyTypeClass1>()
.Named("MyTypeClass1")
.LifestyleTransient());
container.Register(
Component.For<IMyType>()
.ImplementedBy<MyTypeClass2>()
.Named("MyTypeClass2")
.LifestyleTransient());
}
}
}
and I have a consuming class :
public class MyConsumingClass : IMyConsumingClass
{
private readonly IList<IMyType> _myObjects;
public MyConsumingClass(IEnumerable<IMyType> myObjects)
{
_myObjects = myObjects.ToList();
}
}
however at runtime I receive following exception :
Can't create component 'MyConsumingClass' as it has dependencies to be satisfied. 'MyConsumingClass' is waiting for the following dependencies: - 'System.Collections.Generic.IEnumerable`1[[IMyType, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' which was not registered.
I think you may need to add a CollectionResolver to your container.
Try:
kernel.Resolver.AddSubResolver(new CollectionResolver(kernel));
I like @shenku's answer and I'd add this note as a comment, but I can't since I'm a newb. (<50 reputation). Don't mark me as an answer! :)
When you add the sub resolver consider adding the optional parameter for allowing empty collections to resolve correctly as well.
kernel.Resolver.AddSubResolver(new CollectionResolver(kernel, true));
