C#Unity2:使用lifetimemanager时解决genrics问题

我正在使用ASP MVC 3(RC)与Unity 2取得巨大成功。然而,我有一个问题,我不能包扎我的头。在幕后,我使用POCO(个人,公司,…)通过存储库访问。存储库作为泛型(EFRepository)创建,并使用上下文。如果通用存储库类型上没有LifetimeManager,则一切都将按预期工作:

        var container = new UnityContainer();
        container
            .RegisterType<ObjectContext, DataLayerContext>(
                new HttpRequestLifetimeManager<ObjectContext>())
            .RegisterType(typeof(IRepository<>), typeof(EFRepository<>))

        //Works
        var unitOfWork = (IUnitOfWork)DependencyResolver.Current.GetService<IUnitOfWork>());
        //Works
        var webPersonRepository = (IRepository<WebPerson>)DependencyResolver.Current.GetService<IRepository<WebPerson>>();

但是,将LifetimeManager添加到存储库时,解析也会失败:

        var container = new UnityContainer();
        container
            .RegisterType<ObjectContext, DataLayerContext>(
                new HttpRequestLifetimeManager<ObjectContext>())
            .RegisterType(typeof(IRepository<>), typeof(EFRepository<>),
                new HttpRequestLifetimeManager(typeof(IRepository<>)))

        //Works
        var unitOfWork = (IUnitOfWork)DependencyResolver.Current.GetService<IUnitOfWork>());
        //Does NOT work anymore!
        var webPersonRepository = (IRepository<WebPerson>)DependencyResolver.Current.GetService<IRepository<WebPerson>>();

有什么想法吗?HttpRequestLifetimeManager的实现非常标准:

public class HttpRequestLifetimeManager<T> : HttpRequestLifetimeManager
{
    public HttpRequestLifetimeManager() : base(typeof(T))
    {

    }
}

public class HttpRequestLifetimeManager : LifetimeManager, IDisposable
{
    private readonly string _key;

    public HttpRequestLifetimeManager(Type T)
    {
        _key = @"HttpRequestContextLifetimeManager" + T.Name;
    }

    public override object GetValue()
    {
        return HttpContext.Current.Items[_key];
    }

    public override void RemoveValue()
    {
        HttpContext.Current.Items.Remove(_key);
    }
    public override void SetValue(object newValue)
    {
        HttpContext.Current.Items[_key] = newValue;
    }
    public void Dispose()
    {
        RemoveValue();
    }
}

任何帮助都将不胜感激!

谢谢! /维克多
