If you update the app without uninstalling then the application data won't be removed.

If the user uninstalls the app then the local application data will be removed. Roamed data will be removed from the local machine but will persist in the cloud for some time after the last installation is removed. This allows the user to uninstall and reinstall while maintaining the roamed data.

we tried with sample application not working , it is giving the following error. Please help us .

We are getting following Error

Installing package...

(Exception from HRESULT: 0x80073CF9)

The current user has already installed an unpackaged version of this app. A packaged version cannot replace this. The

This generally occurs when you mix development and deployed installs of the app.

Please see Prashant's blog entry Registration of the app failed. Another user has already installed a packaged version of this app. An unpackaged version cannot replace this… for more details and information on how to clean it up.
