I have an SharePoint provider hosted app. In my developement eniorement I added some new Columns to a list. After a deploy I added a new list to the SharePoint App.
I consider that after I deploy the app from Visual Studio (hit F5) that the already existing lists are empty. This happens only if the app is modified (like adding a list or s.th.).
How can I prevent this? because when I add a new feature to my app. I think the customers won't be happy if their data is lost after an update.
