推服务器和客户端应用程序之间的通知机制 [英] Push Notification mechanism between a server and a client app

问题描述

我的深化发展使用C＃，其中有超过一个WCF Web服务的服务器进行通信的桌面应用程序。它应该是一种同步的应用。这意味着，当我在做客户端应用程序的一些变化，我应该也立即更新服务器（这是很容易使用服务调用），也该机制应提供反之亦然，在服务器上的改变必须立即在多个客户端应用。我知道我可以投票给我的服务器，但是这并不显得利落给我，我也听说过双工服务，但我不知道如果我可以用它来实现这种机制。

I am developping a desktop application using C#, which communicates with a server over a WCF Web Service. It is supposed to be a kind of synchronization application. Meaning that when I make some changes on client app I should immediately update the server too(this is easy using service calls), but also this mechanism should be provided vice versa, a change on server must immediately be applied on several clients. I know I can make polling to my server but this doesn't look neat to me, and also I've heard of duplex services, but I'm not sure if I can use it to implement this mechanism.

我要求在这个问题上提出了一些建议。先谢谢了。

I am asking for some suggestions over this issue. Thanks in advance.

推荐答案

您需要实现发布和订阅设计。在WCF，你可以用net-TCP协议在双工客户端和服务器连接

You need to implement a publish and subscribe design. In WCF you could use net-tcp protocol to connect in duplex clients and server.
