Why has ESRI released ArcObjects 10.9.1 when their are no plans to release ArcGIS Desktop 10.9.1? We have some projects developed using 10.8.1 ArcObjects .NET SDK & we are planning to upgrade them to 10.9.1. Some projects are addins based projects & some are standalone desktop applications developed using ArcGIS engine. 

My question is it possible to upgrade all the above applications to 10.9.1 ArcObjects for .NET or Not???

And also why ESRI released ArcObjects 10.9.1 when their are no plans to release ArcGIS Desktop 10.9.1???

Hi,

ArcGIS Enterprise 10.9.1 (server) is based on ArcObjects 10.9.1. You can still develop extensions for ArcGIS Enterprise 10.9.1 using ArcObjects.

It is not possible to upgrade desktop applications code to 10.9.1 ArcObjects.
