Subject: [Resource Guide] How to Download and Install ArcObjects SDK 10.8 (.NET)
Hi everyone,
With the release of ArcGIS Desktop 10.8, many developers are looking to get their hands on the specific ArcObjects SDK to maintain legacy add-ins or build new tools for the classic ArcMap environment.
Since ArcGIS Pro and the ArcGIS Runtime SDKs have taken the spotlight in recent years, finding the download link for the older ArcObjects SDK can sometimes feel like a scavenger hunt. Here is a quick guide to getting set up with version 10.8.
If you are starting a new project, do not use ArcObjects 10.8. Esri has officially retired ArcMap/ArcObjects. The technology is in "Mature Support," meaning it receives no new features and only critical security patches.
If you have a legacy application that is broken and you need the SDK to rebuild it, follow the My Esri route above.
If you are building something new, the "solid story" is that you need to pivot to the ArcGIS Pro SDK. That is the modern, supported path where downloads are public, documentation is active, and the technology aligns with current Visual Studio versions.
Getting Started with ArcObjects SDK 10.8: A Quick Guide If you are maintaining legacy ArcMap applications or building custom extensions for the final series of ArcGIS Desktop, the ArcObjects SDK 10.8 is your essential toolkit. As ArcGIS Desktop moves into its mature support phase, ensuring you have the right development environment is more critical than ever. Where to Download ArcObjects SDK 10.8
