My Scenario:
I have a SharePoint-hosted app with several Lists, Content Types and Site Columns. Now I would like to add some new choices to an existing Site Column (Choice Field).
The Problem:
When upgrading the app, only the Site Column and the Site Content Types are updated. The List Content Types and the List Columns still have the old choices.
The questions:
- Is there a declarative way to push down the changes to the List instances?
- Is there a mechanism to catch the upgrade event to inject custom CSOM code?
