I’m working on a project that relies heavily on communication between multiple WP7 devices. I wanted to use WCF callback contracts to create a subscribe/unsubscribe architecture for my services however I have recently found out that I can’t use wsDualHttpBinding on Windows Phone 7 but only basicHttpBinding.
Can anyone suggest any approaches using basicHttpBinding which might allow for a similar approach?
You could always use Push Notifications to send the data to the phone (the other option would be polling the server at a predetermined interval which would kill battery life on the device).
