Is there any way to communicate with ArcGIS Pro from another application? What I'm looking for is basically having a link in another application that either opens ArcGIS Pro with some parameters or talks to a running ArcGIS Pro instance. In ArcGIS Pro, an addin of ours would receive these parameters and (e. g.) zoom to a specific location or run a certain query. (Specifically, we're talking about a project management application where some projects are linked to certain locations / geo objects that we'd like to show in ArcGIS Pro for further analysis or custom workflows.)
As a workaround, we could define a shared folder where the other application could create a file with instructions and our addin (using FileSystemWatcher or similar) reacts to new files and handles whatever is neccessary. That seems a bit complicated, though. What would be nice would be some kind of URI scheme that's specific to ArcGIS Pro (something like file:/// or http://, maybe arcgis://).
