Silverlight / WPF - Sending data to a Silverlight application from outside

Hi,

I want to develop a multiplayer game.

The game will provide communication between Silverlight application (internet application) and android cellular (client application – like Windows Forms Application).

So actually a user can be a Silverlight application (internet application) or a cellular client application.

The users will send each other XML in order to communicate.

Is it possible to send a data (XML) to a Silverlight application from outside (through IP and Port or any other way)?

I know the Silverlight application can ask the server any X seconds – "Do you have something for me?" – But I do not want to use this approach, because it adds burden on the communication.

Any help will be appreciated.

Hi Peter,

First, thanks a lot for your quick and helpful answer!

I thought to use a central service which will handle the communication between the users
 ((1) Silverlight to Android and (2) Android to Android).

The service will be implemented using WCF.

I read a little about Silverlight polling duplex feature, and I understood that it might have problems (like speed, latency) when used by a medium number of concurrent users.

I read pushing data (XML) to the Silverlight user can be done also using web socket.

Do you think Silverlight polling duplex feature is better in my case? Can you explain why?

Thanks in advance.
