I'm having a problem querying keys after I close and re-open my WP7 app.
The first time I run my app (in the emulator) I download some data from a webservice and save it to a database (including a flush).
When I query the keys I get a result back.
If I close the app and run it a second time in the emulator the same query returns nothing.
I'm guessing I need to do something to load the keys out of the database that has been serialised to the iso store.
