With .NET Core 3.0, we’re at the point where we’ve ported all technologies that are required for modern workloads, be that desktop apps, mobile apps, console apps, web sites, or cloud services. That’s not to say that we don’t have any gaps or opportunities for new technologies, but we generally believe we won’t be finding them in the .NET Framework code base anymore. Moving forward, we’re focusing our resources on incorporating new technologies.

As an almost-20-year hard-core Linux zealot, who watched, in horror, what Microsoft did to the burgeoning personal computing market in the 90’s and early 00’s, I will probably be suspicious of everything they do for the rest of my career. I will never “forgive” them (as if that’s a thing) for funding the SCO v. IBM fiasco, and I still want to know who was involved in that scheme. That being said, even I have a hard time being cynical about .NET Core. This seems to be a good vision and direction, and they are executing very quickly on it. They are delivering what Mono might have been, if more “weight” had been behind it.
