WCF协定可以使用多个回调接口吗?

wcf .net

我正在尝试这样的方法:

[ServiceContract (
    CallbackContract = typeof (CallbackContract_1),
    CallbackContract = typeof (CallbackContract_2),
    CallbackContract = typeof (CallbackContract_3))
]
public interface SomeWcfContract {

我知道这样不管用。有没有一种方法可以让一个合同使用多个回调接口?

服务合同只能指定如果合同是所有回调的子接口合同定义的合同拥有基础合同。

interface ICallbackContract1
{...}

interface ICallbackContract2 : ICallbackContract1
{...}

[ServiceContract(CallbackContract = typeof(ICallbackContract1))]
interface IMyBaseContract
{...}

[ServiceContract(CallbackContract = typeof(ICallbackContract2))]
interface IMySubContract : IMyBaseContract
{...}

或

interface ICallbackContract1
{...}
interface ICallbackContract2
{...}
interface ICallbackContract3 : ICallbackContract2,ICallbackContract1
{...}

[ServiceContract(CallbackContract = typeof(ICallbackContract1))]
interface IMyBaseContract1
{...}
[ServiceContract(CallbackContract = typeof(ICallbackContract2))]
interface IMyBaseContract2
{...}
[ServiceContract(CallbackContract = typeof(ICallbackContract3))]
interface IMySubContract : IMyBaseContract1,IMyBaseContract2
{...}
