During development is often useful to delete the saved data. Here are a couple ways you can accomplish this task:
- You can try to uninstall your app and reinstall it
Another alternative is:
- Go to %localappdata%\Packages\<packageID>
- Note: “%localappdata%” is “%USERPROFILE%\AppData\Local”. For example c:\users\rick\AppData\Local
- Search closely for your file names under LocalState/RoamingState and delete them. Double check that other folders don’t have your files either.
