Christopher,
Thanks for responding. Yes, I have already studied the "Migrating to ArcGIS Pro" document, In fact I was quite thrilled to find it, and then very disappointed when I looked at the content. "Migration" is not addressed at all, this is truly a "Getting Started" (from scratch) document. For those of us that have spent years learning, developing, and refining our knowledge of customizing ArcGIS UnPro (ArcMap), there is little if anything that helps us apply those hard-won skills to migrating. Clearly, while Pro is a completely different animal and many things are different, there are still many concepts and approaches that are still the exactly the same even if they are just sporting new names and terminology.
And yes, what I have been able to do so far has been because of the community samples. Indeed, samples are the lifeblood of a GIS Engineer that needs to have many GIS skills that are not programming related, yet still needs to use programming as just another tool to accomplish a larger task by cobbling together bits and pieces borrowed from samples.
I am looking forward to the resumption of real (not online) instructor-led training.
I have looked at several of the DevSummit videos, and even paused them to painstakingly copy some code to a file. It would be great if any code from these videos were made available digitally. Please don't mention PDF, the bane of all GIS datahounds.
