Why is it bad that it is embedded in the .NET ecosystem?

Doesn't have the same kind of large and innovative ecosystem around it, like competitors such as the JVM.

It's true the JVM has a large ecosystem, but the .NET one is still pretty substantial. I would also argue there's a fair bit of innovation in the .NET Core world :)

They need to make it more visible if there is! I think it's pretty rare to see a .NET paper. I can't remember the last time I saw one, where there are tons of major JVM research projects.

The innovation in the .net world tends to be by companies in the .NET ecosystem, which historically have not been focused on open source or open research. Improvements in the microsoft world tend to be private.

Yeah. This is probably my only beef with .NET ecosystem. There are a lot of great open source libraries and whatnot, but what you see comparatively little of is core systems a lot of software depends on being written in .NET Core. I'm mainly thinking about all the type of stuff you see in the Apache Foundation.

The language itself is incredible, and just keeps getting better and better with every release.

It'd be neat to see people turning to .NET when writing those kinds of systems, but maybe it's just not cool enough in the Bay Area.

I can't say I know what's happening with the CLR itself, but they've shipped several major improvements in the language, server, standard library etc that have brought significant performance gains which make .NET Core one of those most performant stacks on the market.

It feels like .NET focuses primarily on the library and language side of things. In C# you can write surprisingly low-level optimized code. See the introduction of Span<T> for instance: https://docs.microsoft.com/en-us/archive/msdn-magazine/2018/.... Or huge lists of improvements such as https://devblogs.microsoft.com/dotnet/performance-improvemen....

This is in contrast to the JVM where Java is showing its age, but mountains of work poured into the JVM keep it performant: OpenJ9 and Hotspot, Project Loom, Zero GC, as well as big non-Oracle investment such as Shenandoah GC contributed by Redhat, etc.

the emphasis is on "deeply".

I think .NET can be quite an advantage, as stated also in the article.

but if I want to, say, set up a dev environment on linux, it comes with a set of quite different dependencies than what other languages use.

I'm using F# and .NET Core on Linux and I actually really like it. I can use my Linux distribution package manager to install different SDK versions side by side (at the moment, 2.1, 2.2, 3.0, 3.1) and the CLI tools automatically picks up the correct version for each solution. I find it superior to other languages like Rust/Erlang/Python where you need to use a tool that manages the SDKs outside of the distro package manager.

What do you mean? There are .debs and .rpms to install .NET Core on Linux just like any other language

Yeah... I thought it's quite simple also. Rider also works on Linux. It's been a great experience for me.
