20/03/2011 UPDATE: code samples after changes to WP7Contrib code base. Simply I want to show how we do communication with web services when using WP7Contrib. When using web services from WP7 devices you have several options on how you are going to communicate with the service. What follows are the steps required to achieve this using the WP7Contrib. We show how to use a third party web service and how this pattern is very advantageous in this scenario. We aren't advocating this is a better approach than using WCF data services (or any of other implementation), we've just been burnt before by WCF and prefer to possibly go through the pain of hand crafting resources (DTOs) than deal with WCF configs and it's short comings in Silverlight. In Silverlight as we all know communication with web services has to be asynchronous, this in it's self is not a problem, but it can make the code ugly at best and difficult to understand. This is where Reactive Extension...
