In this scenario, we have 2 different applications (admin and client). Both in Silverlight 3, and we have a WCF service (3.5.) The service gets information from the database when the admin app requests is, then, it should update the client application (in a different web browser of course), and the client application should do some operations in response to that update.
What would be the best message exchange pattern to achieve this in the simplest way? We already solved it using a duplex MEP, but we thought maybe we don't need that as loon as the client application is subscribed to the service, and the app application tells the service to update the client application.
Any suggestions?
