WCF Duplex for a Poker Room

Venerdì 24 Aprile 2009 13:33

In italy we are knowing an explosion of poker texas hold'em virtual rooms . So I want to explore this kind of applications.

The first thing to do to build a poker room application is the communication frame.

When you play at poker you need that the server ( the dealer ) pushs some data in broadcast ( flop, bets and other for the rendering on the client side), something else on a single channel (i.e. client cards )

and then in some cases you need that the client can push his bets or other actions ( this could be done on demand too, but I want try with a duplex service :-) ), so we need a quite complex communication system.

the structure of the application could be the following one ( maybe it will change ) :

1) A Server with a WCF Service

2) Client WPF or Silvelight ( we will se later what are limitations of both)

3) Maybe Flex client too...

In this first part I want concentrate on the Service and the communication with clients that will be handled with WCF technology. I chose a duplex channel, yes I want to make me hard the way. Duplex duplex...oh my god...

Let's start to build the service.

WCF Service endpoints

Lunedì 19 Gennaio 2009 21:15

WCF is the new .NET way to define a web communication between server and client.

WCF follows the trend of WPF to build static parts ( configuration ) using a sort of Xml, but that could be replied by code.

This is a brief introduction to how configure a service using the paradigm of WCF : endpoints based on address,binding, contract.

Creating a WCF VisualStudio project it will be very easy to configure the service as follow.

Every service is associated with an address that defines where the service is, a binding

that defines how to communicate with the service, and a contract that defines

what the service does. WCF formalizes this relationship in the form of an endpoint.

The endpoint is the fusion of the address, contract, and binding.
