Dependencies waiting to be satisifed - asp.net-mvc-3

Question

I'm trying to abstract some simple tasks for some very simple objects.
In my domain model, there are a number of different objects which basically serve as a way to tag (classify) a "Program." The Business Logic says a program can have as many of these as its wants, but no tags of the same type (e.g., "County") can have the same name, and you can't delete a tag while it has programs linked to it.
This is built on MVC3 with S#arp 2.0.
The domain model has an abstract base class NamedEntity : Entity which defines
public string Name { get; set; }
among other properties.
Specific types extend this class to add whatever makes them unique (if anything), such as Topic, which is a heirarchical structure and so has additional properties for that.
I wanted to create INamedEntityTasks<T> where T: NamedEntity and then have a base version of this for handling routine tasks like bool CheckForDuplicateName(string Name) which would run access its INamedEntityQueries<T> object and call T FindByName(string Name)
If a subclass needed to add more rules prior to delete (e.g. a topic with children can't be deleted), then it just overrides the virtual method from the base class.
Structure:
MyProject.Infrastructure has INamedEntityQueries<T> and NamedEntityQueries<T> as well as ITopicQueries : INamedEntityQueries<Topic> and TopicQueries: NamedEntityQueries<T>, ITopicQueries
MyProject.Domain.Contracts.Tasks has INamedEntityTasks<T> and ITopicTasks : INamedEntityTasks<Topic>
MyProject.Tasks has NamedEntityTasks<T> and TopicTasks: NamedEntityTasks<Topic>, ITopicTasks
My TopicsController won't run because of a missing dependency that I can't figure out.
The exact exception is
Can't create component
'MyProject.web.mvc.controllers.topicscontroller'
as it has dependencies to be
satisfied.
MyProject.web.mvc.controllers.topicscontroller
is waiting for the following
dependencies:
Services:
- MyProject.Infrastructure.Queries.ITopicQueries
which was not registered.
- MyProject.Domain.Contracts.Tasks.ITopicTasks
which was registered but is also
waiting for dependencies.
MyProject.Tasks.TopicTasks is waiting
for the following dependencies:
Services:
- MyProject.Infrastructure.Queries.INamedEntityQueries`1[[MyProject.Domain.Topic,
MyProject.Domain, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=null]]
which was not registered.
I checked the container in ComponentRegistrar with a breakpoint and it shows 3 potentially misconfigured:
"MyProject.Tasks.NamedEntityTasks`1" NamedEntityTasks`1
"MyProject.Tasks.TopicTasks" ITopicTasks / TopicTasks
"MyProject.web.mvc.controllers.topicscontroller" TopicsController`TopicsController`
Any help would be appreciated.

You don't need the IFooTasks interface, just use an abstract base class, then IFooBarTasks and IFooBazTasks will be registered with Castle Windsor by the standard ComponentRegistrar in S#arp Architecture:
public abstract class Foo
{
public void Foo1();
public void Foo2();
}
public class FooBar : Foo
{
public void FooBar1();
}
public class FooBaz : Foo
{
public void FooBaz1();
}
public interface IFooTasks
{
void Foo1();
void Foo2();
}
public interface IFooBarTasks : IFooTasks
{
void FooBar1();
}
public interface IFooBazTasks : IFooTasks
{
void FooBaz1();
}
public abstract class FooTasks : IFooTasks
{
public void Foo1()
{
// Foo1 implementation
}
public void Foo2()
{
// Foo2 implementation
}
}
public class FooBarTasks : FooTasks, IFooBarTasks
{
public void FooBar1()
{
// FooBar1 implementation
}
}
public class FooBazTasks : FooTasks, IFooBazTasks
{
public void FooBaz1()
{
// FooBaz1 implementation
}
}
