Exemplo manual IDependencyResolver

MeuDependencyResolver.cs

public class MeuDependencyResolver : IDependencyResolver
{
    private HashSet<object> dependencias;

    public MeuDependencyResolver()
    {
        this.dependencias.Add(new DummyDependencia1());
        this.dependencias.Add(new DummyDependencia2());
        this.dependencias.Add(new DummyDependencia2_2());
    }

    public object GetService(Type serviceType)
    {
        return this.dependencias.ToLookup(l => l.GetType())[serviceType].FirstOrDefault();
    }

    public IEnumerable<object> GetServices(Type serviceType)
    {
        return this.dependencias.Where(t => t.GetType() == serviceType).ToList();
    }
}

Opa!! Dei uma refatorada, o legal é que agora o container pode conter mais de um controller com dependências diferentes.
