PubNub is a new real-time cloud-based subscribe/publish API, it requires no servers, minimal setup and it has a cross-platform API including JS, PHP and C#.
I downloaded the sample solution, which includes PubNub clients for C# based languages, including MS Windows C#/.NET, Silveright, IIS, and Mono:
Then this is what you have to do to make it work:
Go to http://pubnub.com/free-trial to activate a trial.
Activate the trial by clicking on the link in your email:
You will be redirected to the Admin Portal:
Make note of the following keys:
– Subscribe key
– Publish key
The secret key is only needed for encrypted messages, which is not part of this demo.
Take the solution you downloaded from:
Unzip and open the solution in:
Build the solution. Notice the PubNubMessaging.Core.exe in
Create a new Console Application, and add a reference to this PubNubMessaging.Core.Exe.
Now in Program.cs:
You only have to change the following constants:
// Make this up yourself
const string CHANNELNAME = “XXXXXXXXXXXXXXXX”;
// for example “pub-c-4743ca37-2480-425a-391f-ab01dbcd281a”
const string PUBLISH_KEY = “XXXXXXXXXXXXXXXXXXXXXXXXX”;
// for example “sub-c-cf6199f3-ba1a-11e2-89ba-02ee2dcab7ff”
const string SUBSCRIBE_KEY = “XXXXXXXXXXXXXXXXXXXXXXXXX”;
You can make up the Channel Name yourself.
The Publish key and Subscribe key are the keys you got in the Admin Portal.
If you want a more elaborate sample, create a new Console Application and add the package “PubNub C# Web Data Push API” to your application using the NuGet Package Manager. Then you will see the following files in your project:
PubNub.cs (the code that does the interfacing to PubNub for you)
PubNubExample.cs (the sample code)
And also a reference to “Newtonsoft.Json.dll”.
The only thing you have to do to make it work is to replace “demo”, “demo” with your Publish key and Subscribe key.
pubnub = new Pubnub("demo", "demo", "", cipheryKey, (enableSSL.Trim().ToLower() == "y") ? true : false);
