Is it possible to develop an AddIn using ArcGIS Pro SDK for .Net version 3.3.0.52636 that can be used with older versions of ArcPro (specifically 3.1)? If so, how do I configure an AddIn to do this?
this is not supported.
I have a separate pc that I use for 3.2 builds. I need to keep .NET 6 in that project, and the extension's auto-update feature off. I downloaded and installed the older 3.2 version of the SDK and keep it on 3.2 version, since it is not possible to downgrade the extension.
Hope this helps.
