This week I’ve been working on the Background Agents for PictureMe Universe on Windows Phone 7. I had some interesting issues with the Isolated Storage not acting the way I had hoped with regard to being global through my app. That said, this week the “global Isolated Storage” issue went away by loading a fresh version of PictureMe Universe (app) onto the device and stopping the debugger, then testing. Isolated Storage seems to “reset” once I stop debugging. So for example, if you have an application where you’d like the user to “sign up” and then save some data for a persistent login every time the user returns to the app, I recommend stopping the debugger (once you have the other nuances smoothed out already) to test the persistent login functionality. Hope this helps someone experiencing the same issue.
