Actually, if you implement the WCF service that notifies if there is a new content as a WCF Duplex, you can do it whenever you need, no matter if it is a second after the previous update, because the Client(your app) will connect to the service when it opens and the service will invoke a callback once a new update is available, this will trigger the Updater to download the new content into your module like folder, then your observer class will just do the rest... NOTE: this update will only ADD new content, it wont update previous content, so you need to analyze that scenario too.

Hope this helps.
