不能将佣金问题应用于组件后期绑定，因为它似乎是一个无目标代理。目前不支持这些

Question

我设计了一个简单的单元测试模式并使用了 moq 库。但是执行Container.Resolve<IInterface>()方法时抛出异常。以下为温莎城堡报名方式：

container.Register(Component.For<TBase>().UsingFactoryMethod(() =>
{
    var mockObject = new Mock<TBase>();
    var mockType = typeof(TBase);

    if (container is Core.IoCContainer.IoCCore.CustomContainer)
    {
        var resolvingDelege = (container as Core.IoCContainer.IoCCore.CustomContainer).ResolvingTestDelegateList[mockType];

        if (resolvingDelege != null)
        {
            resolvingDelege(mockType, mockObject);
        }
    }

    return mockObject.Object;
})
.LifestyleTransient());

执行IoCCore.Container.Resolve< ISampleDataContext>();时，抛出异常。异常消息是 "Can not apply commission concerns to component Late bound Data.Context.ISampleDataContext because it appears to be a target-less proxy. Currently those are not supported."

我搜索了一下问题，发现mockObject.Object是Castle.DynamicProxy.IProxyTargetAccessor。因此，在解析实例时，下面 Castle.MicroKernel.ComponentActivator.AbstractComponentActivator class 中的代码是问题发生的地方：

protected virtual void ApplyCommissionConcerns(object instance)
    {
        if (Model.Lifecycle.HasCommissionConcerns == false)
        {
            return;
        }

        instance = ProxyUtil.GetUnproxiedInstance(instance);
        if (instance == null)
        {
            // see http://issues.castleproject.org/issue/IOC-332 for details
            throw new NotSupportedException(string.Format("Can not apply commission concerns to component {0} because it appears to be a target-less proxy. Currently those are not supported.", Model.Name));
        }
        ApplyConcerns(Model.Lifecycle.CommissionConcerns, instance);
    }

UsingFactoryMethod正在解析的对象是Castle.DynamicProxy.IProxyTargetAccessor，它是由模拟对象创建的。但是，Castle Windsor 假设 IProxyTargetAccessor 是由它自己创建的，而不是模拟对象。这会导致 CommissionConcerns 的空实例从我的模拟实例返回。

这个错误是否有可能的解决方法？我应该等待更新吗？

我针对这个问题制定了解决方法。我更改了 UseFactoryMethod 方法而不是下面的代码

Component.For<TBase>().UsingFactoryMethod(() =>
            {
                var mockObject = new Mock<TBase>();
                var mockType = typeof(TBase);

                if (container is Core.IoCContainer.IoCCore.CustomContainer)
                {
                    var resolvingDelege = (container as Core.IoCContainer.IoCCore.CustomContainer).ResolvingTestDelegateList[mockType];

                    if (resolvingDelege != null)
                    {
                        resolvingDelege(mockType, mockObject);
                    }
                }

                //The code that was changed
                //==============================================
                var type = mockObject.Object.GetType();
                var field = type.GetField("__target");

                field.SetValue(mockObject.Object, new Object());
                //==============================================

                return mockObject.Object;
            })
            .LifestyleTransient());
