C# 基于任务的异步模式不支持System.IProgress

我有一个WCF服务，IMyService。在此服务中，有一个操作使用System.IProgress

public async Task MyOperation(int id, IProgress<long> progress)

public异步任务MyOperation（int-id，IProgress-progress）

我使用Autofac为IMyService服务创建了一个客户端

builder.Register(c => c.Resolve<ChannelFactory<IMyService>>().CreateChannelWithIssuedToken(xmlToken)).As<IMyService>()

builder.Register（c=>c.Resolve（）.CreateChannelWithIssuedToken（xmlToken））.As（）

现在，我收到这个错误：

错误是关于基于任务的异步模式不支持IProgress。这似乎不对，有人能帮忙吗。

IProgress

用于进程内通信，而不是internet通信。作为WCF服务调用是不明智的；协议不支持这种类型的通信。
