In this post Gill Cleeren takes a look at Silverlight’s Isolated Storage and shows what can be done with this handy option.
Isolated storage does not differ that much from cookies. It’s basically a file store for Silverlight: Silverlight applications can store in the Isolated Storage files during a session and retrieve them in a later session. Isolated storage is a per-user per-application storage, meaning that when userA works with SilverlightAppA, he’ll have a different isolated storage from userB working with the same application. Isolated storage information is not deleted when you clear your temporary internet files, it can be deleted through the Silverlight configuration.
