为什么未经我的许可就处置我的自动常见问题范围？

Question

我正在尝试在我的dot net项目中使用auto-fac来处理依赖关系。我创建了scopeContainer来管理在程序中单击“新建”时重置范围。不知何故，我的ChildScope在不经接触的情况下被处置。是否有任何autofac功能会在我不知情的情况下处理我的ChildScope？

ScopeContainer：

        /// <summary>

        /// </summary>
        private static ILifetimeScope _baseScope;

        {
            Bootstrapper = new Bootstrapper();
            Bootstrapper.Configure();
            _baseScope = Bootstrapper.Container.BeginLifetimeScope(ContainerConstants.SCOPE_BASESCOPE);
