I tried posting this in the general ArcGIS Pro area. But maybe this is a more appropriate place:
Are there any plans to support geoprocessing in a stand-alone ArcGIS Pro SDK CoreHost app?
I watched the DevSummit21 day 3 plenary. And this was mentioned, but I'm not sure if he misspoke.
Anyway this is definitely something which we could use - we are currently using ArcObject/Engine for this scenario.
