Why can't I save/delete annotations using CoreHost?

Question

Environment/Project

* ArcGIS Pro 2.6
* .NET Framework 4.8 CoreHost referencing ArcGIS.Core 12.6.0

Problems

* AnnotationFeature setters (e.g. SetGraphic(), SetStatus(), etc) and Store() wrapped in ApplyEdits() does not save edits to the database. No exceptions are thrown.
* AnnotationFeatureClass DeleteRows() wrapped in ApplyEdits() throws a geodatabase exception if Element field is null.

Workaround

Do not wrap annotation saves/deletes within ApplyEdits().

Is this the expected behavior?

This is fixed in the just-released ArcGIS Pro 2.7

This should be fixed in Pro 2.7.  Note that this behavior applies to all editing done inside Geodatabase.ApplyEdits() on services that do not support version management, not just annotation edits.

Sung Bae‌ Thanks for bringing this to our attention. We have logged the issue as a bug in our internal bug tracking system and development team will investigates the cause of this behavior. You can use the workaround until it is fixed.
