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).
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.
- 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?
