Is it possible to access the functions or properties of an ArcGIS Add-in project (C#) from another Add-in at run time?
I have a custom ArcMap application extension installed and I would like an Add-in command from a different project to check if the extension is enabled and if so read/write a property from it.
I have seen this help doc but it only talks about communication within the same project. Add-in coding patterns
So far the only way I know how to do this is to add a reference for the extension's dll to the other Add-in projects. I'd like to set it up to be independent though.
I'm using ArcGIS 10.4.1 and VS 2015 if it matters.
