We are using MapObjects in windows service and it seems to be working flawless in terms of data updates to SDE. We wanted to migrate it to ArcObjects. What will be the best option to use ArcObjects in our Windows Service?
Technically speaking, I think that Engine would be the way to go. The problem with this approach is that I believe that it may well violate contractual terms and conditions.
I belive, and your link confirms, that ESRI wants you to use ArcGIS Server.
