The demo demonstrates an approach using a stream
to save the persisted data. You can save this stream in a database as this will allow you to get the value of the stream from your database during different sessions.
Also, the PersistenceFramework
allows you to save the persisted data in an IsolatedStorage
. With this approach you will be able to access the files containing the persisted data from the isolated storage whenever you need them, even during different sessions.
I hope this information helps but do write back in case you need further assistance.
