Whither ArcObjects?

Question

Circa 2010, with ArcGIS Desktop 10, the new add-in platform was released. Use .NET programming to develop add-ins for ArcMap! Books were published, classes were held. I wrote some pretty cool add-ins in C# with ArcObjects to help my company's workflow, in roughly the period 2010-2014.

Nowadays, I can barely find any references to the ArcObjects SDK for C# .NET. It's all Python all the time, or the Runtime SDKs, or WPF and Pro.

I love Python, and I love ArcGIS Pro, but what is the future of ArcObjects .NET development for ArcMap? There seem to be many things I cannot do with Python add-ins that I can only accomplish with aging .NET add-ins that I can no longer effectively debug/modify because the documentation is receding into the wilderness and Visual Studio support is increasingly lacking.

What's a .NET add-in developer to do?

I would agree the documentation has always been lackluster, but the forums have always made up for it. My biggest complaint is that with every release ESRI scraps the existing forums and introduces a new version. Over the years tons of great information was shared on the forums in their various incarnations: the original green arcobjects forum, edn (the red one), etc. It was a pain, but they at least they were still online and searchable if you knew where to look. When those were taken down, years of knowledge acquired from trial and error was lost. This latest incarnation is time consuming to browse, highly fractured, and difficult to view from a macro perspective.

I think ESRI is just following the market.  Python scripting in ESRI products was intended to replace VBA, which was a steeper learning curve for non-programmers and locked ESRI into needing Microsoft since VBA is a Microsoft product.

The API will not go away.  There are still way too many people who want to integrate ESRI products into their programs and Python can't really do that (yet).  As long as there is Windows, Unix and IOS, the API will be necessary, so it will exist and need to be supported.

I'm not totally sure I agree with your observation that the documentation is disappearing.  I think the documentation hasn't always been exceptional to begin with, but it has always been there and it is maintained.  Once you get used to how ESRI does things, it always ends up so that not much trial and error is necessary to get things working.  And occasionaly the forums will find you someone who has worked with the interface before and has a suggestion.

I think many organisations have invested in custom extensions and whilst arcgis pro is still "catching up" with arcmap functionality I can see a real need for us desktop developers. Also I hear what you are saying about web gis but much of my work is processing data and desktop still rules the roost in my mind.

Web gis seems to require one to be an expert in web servers, databases, html, browsers, network technology and then gis concepts. So I think desktop needs to be around and hopefully arcobjects.
