I think we'll need to disagree, as we have incompatible views on what the reality is. I absolutely do not dispute that anyone involved in building Windows-only desktop apps is not going to be satisfied - but they are absolutely in the minority. As a consultant, I don't just see the workings of a single org - I work across several orgs every year. When Core first became a thing, some were slow to take it on, which was understandable considering the confusing messaging from Microsoft. But it's been around for a long time now, and Microsoft's messaging and intentions became clear. What I now seen is huge uptake of Dotnet Core - way, way more is now on Core than Framework, and I haven't seen anything new being built on Framework for at least a couple of years.
