my problem is that i am trying to write a program that sends data to clients via wcf.

i have read a lot about it and finally i saw this topic in code project: http://www.codeproject.com/Articles/34333/Topic-based-publish-subscribe-design-pattern-imp

i have implemented it so it will be good to my needs. the problems are:

  1. i have multiple clients and there is some messages that i need to notify only one client and not all of them.
  2. sometimes i want my client to receive a message from the server,do something and then reply another message to the server

thanks ahead for the help

    You can use `Dictionary` to register all clients and store callback channels to them as values. Later you can get some of these values by using specific Key. And use channel to send some message or invoke action using RPC. – Fabjan Oct 21 '15 at 14:45

  1. Set an id for your clients. And then just include id (or id collection) into your messages, so clients can filter messages.
  2. I guess you can develop your client so it can be both publisher and subscriber? Not sure what is the problem here
