C# Ninject-请求范围已被释放

我正在MVC 3应用程序中使用

Ninject

和扩展EventBroker和DependencyCreation。我已经安装并正在使用Ninject.MVC3软件包，因此使用了

OnePerRequestModule

我正在尝试将名为

IParentService

的服务注入控制器

IParentService

依赖于通过DependencyCreation扩展创建的

ChildService

（无硬引用）

这两个服务都在本地事件代理实例（本地到

ParentService

）上注册

我希望

IParentService

根据请求确定作用域，并且我希望依赖项和事件代理与

IParentService

同时被处置，但是，我得到了一个

ScopeDisposedException

我做错了什么？

一些代码：

服务定义：

public interface IParentService
{
}

public class ParentService : IParentService
{
    [EventPublication("topic://ParentService/MyEvent")]
    public event EventHandler<EventArgs> MyEvent;
}

public class ChildService
{
    [EventSubscription("topic://ParentService/MyEvent", typeof(bbv.Common.EventBroker.Handlers.Publisher))]
    public void OnMyEvent(object sender, EventArgs eventArgs)
    {            
    }
}

[ScopeDisposedException: The requested scope has already been disposed.]
