What do you mean? The .Net ecosystem has been generalized chaos for the past 10 years.

A few years ago even most people actively working in .Net development couldn't tell what the hell was going on. It's better now. I distinctly recall when .Net Framework v4.8 had been released and a few months later .Net Core 3.0 came out and they announced that .Net Standard 2.0 was going to be the last version of that. Nobody had any idea what anything was.

.Net 5 helped a lot. Even then, MS has been releasing new versions of .Net at a breakneck pace. We're on .Net 10, and .Net Core 1.0 was 9 years ago. There's literally been a major version release every year for almost a decade. This is for a standard software framework! v10 is an LTS version of a software framework with all of 3 years of support. Yeah, it's only supported until 2028, and that's the LTS version.

The only chaos occurred in the transition from .NET Framework to .NET (Core). Upgrading .NET versions is mostly painless now because the breaking changes tend to only affect very specific cases. Should take a few minutes to upgrade for most people.
