Can someone explain how the Silverlight 4 OOB upgrades happen? Is it click one? Would the OOB shell automatically download the latest xap from the server?

A:
You need to code up the check for and download upgrades from within your application. You do this using Application.CheckAndDownloadUpdateAsync.
