I have developed an ArcGIS Desktop AddIn for ArcGIS 10.1 using Visual Studio .Net 2010. The AddIn is established, widely used and by all accounts works well. Many folks have also been using it on ArcGIS 10.2 without issue. The one exception is that I call the AggregatePoints geoprocessing tool and this fails on 10.2 with the message:
Could not load the file or assembly 'ESRI.ArcGIS.CartographyTools, Version=10.1.0.0...
As I said, all other operations, including many geoprocessing calls, are working on ArcGIS 10.2 just fine. Before the tool runs, I check that the user is running an ArcInfo (Advanced) license.
Can someone help why this one tool/DLL is an issue on ArcGIS 10.2 please?
