IEventAggregator

Hi 
I am trying to move to Cocktail from DAF. I have almost everything working apart from not being able to import IEventAgregator.

1) No valid exports were found that match the constraint '((exportDefinition.ContractName == "Caliburn.Micro.IEventAggregator") 

I am at a loss as to why it is not being exported.

I have included my Bootstrapper code. Hopefully someone can see what I am doing wrong and needs to be changed. It all worked in the old DAF.

Thanks

 public class WpfBootstrapper : FrameworkBootstrapper<IShell>
    {

        private CompositionContainer _container;

        public WpfBootstrapper()
        {
            // Uncomment to enable Caliburn Micro logging
            // LogManager.GetLog = (Type t) => Torpedo.Geo.Shared.Helper.CaliburnDebugLog.GetInstanceForType(t);
        }

        protected override void PrepareCompositionContainer(CompositionBatch batch)
        {
            base.PrepareCompositionContainer(batch);

            // batch.AddExportedValue<IWindowManager>(new WindowManager());

            _container = new CompositionContainer(new AggregateCatalog(
                AssemblySource.Instance.Select(x => new AssemblyCatalog(x)).OfType<ComposablePartCatalog>()
                ));

            batch.AddExportedValue<IEntityManagerProvider<TorpedoEntities>>(new EntityManagerProvider<TorpedoEntities>());

            batch.AddExportedValue<IAuthenticationService>(new AuthenticationService());

            batch.AddExportedValue<Func<IMessageBox>>(() => _container.GetExportedValue<IMessageBox>());

            batch.AddExportedValue<Func<ILocationViewModel>>(() => _container.GetExportedValue<ILocationViewModel>());

            _container.Compose(batch);

        }

        protected override object GetInstance(Type serviceType, string key)
        {
            string contract = string.IsNullOrEmpty(key) ? AttributedModelServices.GetContractName(serviceType) : key;
            var exports = _container.GetExportedValues<object>(contract);

            if (exports.Count() > 0)
                return exports.First();

            throw new Exception(string.Format("Could not locate any instances of contract {0}.", contract));
        }

        protected override IEnumerable<object> GetAllInstances(Type serviceType)
        {
            return _container.GetExportedValues<object>(AttributedModelServices.GetContractName(serviceType));
        }

            _container.SatisfyImportsOnce(instance);
