    The account that your app’s application pool in IIS is running as needs write access to the App_Data folder where your database file (mdf) is stored. E.g. if the app pool is configured to run as Network Service, give permissions to that account on App_Data folder.

    When you run in the VS host your app is running as your user account which has access to App_Data.
