使用PerThreadLifetimeManager和InjectionFactory

Question

有人可以解释以下示例代码的结果。问题是为什么ThreadContext中已解析的线程ID与当前托管线程ID不匹配？是否在所有托管线程之间缓存和共享了InjectionFactory的结果，即使我使用PerThreadLifetimeManager来为每个线程本地缓存委托结果。

       public class ThreadContext
    {
        public ThreadContext(int id)
        {
            ThreadId = id;
        }

        public int ThreadId { get; set; }
    }

    static void Main(string[] args)
    {
        UnityContainer container = new UnityContainer();

        for (int i = 0; i < 5; i++)
        {
            Task.Factory.StartNew(() => DoWork(container));
        }

        Console.ReadLine();
    }

    private static void DoWork(IUnityContainer container)
    {
        int id = System.Threading.Thread.CurrentThread.ManagedThreadId;

        container.RegisterType<ThreadContext>(new PerThreadLifetimeManager(), new InjectionFactory(_ => new ThreadContext(id)));

        Console.WriteLine(id + " -- The current thread id is  = " + container.Resolve<ThreadContext>().ThreadId);
    }
}
