多个客户端到单个 WF 服务
Windows 工作流服务是否允许多个客户端使用一项服务？基本上我想做的是：构建一个 WF 服务，允许客户端“订阅服务”，然后当某些事件触发处理程序时，它将数据广播到每个客户端。因此，基本上某些事情将在后台处理，然后当服务接收到一个小字符串时，它会通过回调将该字符串广播到每个客户端。
因此，我首先需要弄清楚的是，我是否有一个具有向世界公开的 Subscription() 方法的服务，并且如果我有 3 个客户端调用该方法，则存储有关其回调端点和实现的信息以保留未来的数据”广播”；所有这些都可以在一项 WF 服务中实现吗？如果是这样，我如何在广播回调期间引用我的客户？
Do Windows Workflow Services allow multiple clients to one service? Basically what I am trying to do is this: construct a WF service that allows clients to "subscribe to the service" and then when certain events trigger a handler, it broadcasts data to each client. So basically something is going to process in the background and then when the services receives, lets say a small string, it broadcasts that string to each client via callbacks.
So what I need to figure out first is if I have a service with a Subscription() method exposed to the world and if I have let's say 3 clients call that method, store information about their callback endpoint and implementation to retain for future data "broadcasts"; can all of this happen in one WF service? If so, how do I reference my clients during broadcast callbacks?

我通过在客户端中保存回调服务的实现来解决这个问题。在实际服务中，我有
subscribe()和unsubscribe()服务方法，它们将客户端端点 URI 作为参数之一。对其他参数进行一些身份验证后，URI 将保存到客户端池集合中。为了向所有客户端进行多播，我迭代 URI 集合并为每个 URI 执行回调。I resolved this by saving implementing callback services in the client. On the actual service I have
subscribe()andunsubscribe()service methods that take in the clients endpoint URI as one of the parameters. After some authentication on other parameters, the URI is saved to a client pool collection. To do multicasts back to all clients, I iterate through URI collection and perform callbacks for each URI.
