I'm working on an Add-In for ArcMap 10.0 in .NET version 3.5. This add-in works fine with ArcMap 10.0. Now I want to use this add-in in ArcMap 9.3. But I couldn't add Add-In .dll file in ArcMap 9.3.


Is there any process to use ArcMap 10.0 Add-In in ArcMap 9.3?


The add-in model is a new feature in version 10.0. This means you will not be able to use an add-in at lower versions, which require you to implement your commands, extensions, toolbars etc. in the older COM-only model.

  • Is there any different implement issue in older COM-only model? or I have to just recompile my toolbar in older sdk? – Emi Jul 10 '12 at 9:47

    It's just a different way of extending ArcObjects, which was the only way at 9.3 and can of course still be used at 10. See the documentation for 9.3: resources.esri.com/help/9.3/ArcGISDesktop/dotnet/… – Petr Krebs Jul 10 '12 at 10:31
