I am interested in connecting my android, iOS and flash clients to a wcf service and want to push updates to my clients from the WCF service as and when events regarding the client occurs.
From the google searches, i got weborb.net and flourinefx.net. But these are based on rtmp, so i cant manage push for android and iphone clients.
Is there any alternative for pushing data from WCF service to all of my clients?
You might want to take a look at SignalR. From what I've read it seems like it could do the trick.

I want to write an android application and I want to know if SignalR use websocket or something else for communicating between server and client, before I do that.
Anybody know?
By default, SignalR will try to work with web sockets, if they are not available in the underlying platform, it will fall back to SSE, and then to long polling.
Xamarin/Mono current implementation has some issues with web sockets, even though SignalR supports it, so web sockets will not be available.
If your app is made with Xamarin (as you tagged your question), the best protocol you will get is SSE (server sent events). But in my experience (I´ve got an app working with it) this protocol is fast and stable enough for most use cases.
From the signalR webpage
SignalR uses the new WebSocket transport where available, and falls
back to older transports where necessary.
From the Xamarin forums and youtube, It seems people have successfully implemented websocket transport with SignalR on Android
What else can I use?
Socket.IO for an HTML5 application(With NodeIIS),GCM or Firebase like push notifications for native on any webserver
We are planning to develop a client server application. The server component shall be developed as REST based WCF Services. The server component needs to send some notification to clients... The clients can be any of the following
1- WPF based windows apps
2-ASP.NET web application
3-Android or iOS apps
What is the best way of sending notifications
Thanks in advance
You could use SignalR
It was originally built for ASP.net:
http://signalr.net/
But now also Works for Andriod:

There is also a possibility to use it With a WPF Client:

I'm working on an App that I've made for both iOS and Android. On the iOS side, I use a constant TCP connection and JSON messages for the push notifications. I want to do the same thing for the android version, however I'm not sure if it's possible. I think using the Cloud Connection Server http://developer.android.com/google/gcm/ccs.html is the way to go, however it only shows samples for Java and Python. Is it possible to use this in c++?
You can choose whatever programming language to desire to implement the server side. The question is whether you can find an easy to use XMPP C++ library for connecting to the Cloud Connection Server.
I assume it will be easier to find an HTTP C++ library for sending HTTP requests to the GCM HTTP Connection Server. If you are not planning to use the upstream functionality (device to cloud), you don't need to go though the trouble of implementing/using the XMPP protocol.
I am trying to build a server/web service which provides APIs to Android/iOS client. I am using WCF service and clients can send request to server successfully. Now, I am going to make server enable to ping client to notify that there some changes in server and client need to synchronize data.
The question is: Is it possible to enable my server to ping client (Android/iOS), I knew that it is possible for Windows client by using wsDualHttpBinding but I am not sure about iOS and Android client. Anyone can help me to make it clear? Any solution is appreciated.
I don't think you can do it. For start, while wsDualHttpBinding is intended to be interoperable I don't beleive in practice it is supported by any otehr framework than WCF. Then wsDualHttpBinding uses a client callback url that the server needs to contact. This url is not going to be accessible on a phone. You should use websockets, long polling or some proprietary push mechanism of the device os.
what is the best way to create a two way constant communication between a server and an android app?
When I say constant communication, I mean client asking server for data or server constantly pushing data to clients.
From what I saw, I can't use websockets since they are designer for server/browser setups. Is that right? If so, what is the alternative?
Is there free frameworks to work with this in Android?
What I am trying to do is an application that works like a chatting but for multiple people. So they all will get in one "room or channel" on their devices, and then interact with each other, in a way handdled by the server.
Thanks!
As far as I know , one possible way is using a web service where the client can connect to the server , if the web service is RESTFul there are many libraries to access it , one of them is the apache HTTPClient , for the server pushing the only way I know is C2DM for pushing data to clients.
For continuously-open data connection, you may use Sockets. But you should also consider the fact that an always-open connection will drain your battery quickly too. For more details, read this and this
You may want to look at AutobahnAndroid:
https://github.com/tavendo/AutobahnAndroid
which provides native Android/Java WebSocket client framework (plus WAMP = PubSub/RPC over WebSocket .. http://wamp.ws).
This is fully interoperable with WebSocket servers that server browser clients.
The AutobahnXX libraries (where XX = Python, JS, Android) are Open-Source (Apache 2.0). We (Tavendo) are offering a commercial virtual appliance based on Autobahn: http://autobahn.ws
Disclaimer: I am author of Autobahn and work for Tavendo.
But keeping the connection running on the background on iOS and Android devices does drain the battery, for people who have this issue, I suggest using push notifications when the app is not on the foreground.

Websocket is an IETF/W3C protocol, so it is not confined to a specific client platform. You can use Android websocket to get a two-way communication between Android and server side. For Android websocket client, I recommend using AndroidAsync. It has all websocket API that you need to establish the communication link and exchange data between Android and the server.
