Depends on what you mean by ecosystem, it hasn't been trapped on Windows for about a decade now. The variety of third party libraries available is quite good, while the standard library is robust enough that you don't need NPM nonsense like LeftPad and IsEven and IsNumber.
Are there particular things about the ecosystem that you worry about (or have heard about)? Biggest complaint I would have is that it seems like many popular open source libraries in the .NET ecosystem decide to go closed source and commercial once they get popular enough.
Yup, the commercial libraries. That's pretty big. It's nice the standard library has lots of goodies, but I doubt many projects in reality are zero-dependency
(The amount of times I hear "the standard lib is great!" seems more to attempt to defend the plethora of commercial libraries, more than anything)
The community feels rather insular too? The 9-5 dayjob types with employers who don't understand or embrace open source? At my age I can respect that though
And is Postgresql a 2nd-class citizen? If so, your boss will tell you to use SQL Server surely?
I guess it's hard to get a grasp on the state/health of .NET as to me it seems 99.99999% of the code is in private repos companies, as it's not a popular choice for open source projects. Which itself seems like a proxy signal though
I work with .NET for my day job and my team doesn't use any commercial libraries. I haven't felt limited in any sense by the .NET ecosystem. Nearly everything is open-source, too.
The anemic open source projects are really from the lack of good cross platform support early on. That's changed now but it missed out on a time of rapid OSS expansion that Java and other took in.
It is what it is but I wouldn't say its actually the fault of the language, especially now.
C# is a language that serves many masters and if you trace the origin of its featureset, you can see why each was created. Take the `dynamic` keyword: created to support interfacing with COM interop easier[0].
It serves many audiences so it can feel like the language is a jack of all trades and master of none (because it is) and because it is largely backwards compatible over its 20+ years of existence.
That said, I think people make a mountain out of a molehill with respect to keyword sprawl. Depending on what you're building, you really only need to focus on the slice of the language and platform you're working with. If you don't want to use certain language features...just don't use them?
I think it excels in a few areas: web APIs and EF Core being possibly the best ORM out there. For me, it is "just right". Excellent platform tooling, very stable platform, very good performance, hot reload (good, but not perfect), easy to pick up the language if you already know TypeScript[1]; there are many reasons it is a good language and platform.
> C# is a language that serves many masters and if you trace the origin of its featureset, you can see why each was created. Take the `dynamic` keyword: created to support interfacing with COM interop easier.
VB.NET's Object was created to support interfacing with COM interop easier. VB.NET's one key niche versus C# for many early years was COM interop through Object.
C#'s dynamic keyword was more directly added as a part of the DLR (Dynamic Language Runtime aka System.Dynamic) effort spurred by IronPython. It had the side benefit of making COM interop easier in C#, but the original purpose was better interop with IronPython, IronRuby, and any other DLR language. That's also why under the hood C#'s dynamic keyword supports a lot of DLR complexity/power. You can do a lot of really interesting things with `System.Dynamic.IDynamicMetaObjectProvider` [1]. The DLR's dependency on `System.Linq.Expressions` also points out to how much further in time the DLR was compared to VB.NET's Object which was "just" the VB7 rename of VB6 Variant originally (it did also pick up DLR support).
The DLR hasn't been invested into in a while, but it was really cool and a bit of an interesting "alternate universe" to still explore.
I’m convinced the comment section hates multi-paradigm languages because you can misuse them. And it has features that may not be needed, which triggers this weird purist mentality of, “gee, it would be so much better if it didn’t have feature X.” But oftentimes that’s just pontification for its own sake, and they aren’t really interested in trying it out. Feature X remains something they won’t use, so it should go.
No, it's good at the right thing which is allowing developers to write type-safe SQL queries using C# at the application layer versus writing SQL that gets translated into C#.
What's the relevance here? Some sort of weird "Ha! Gotcha!" I'm certainly aware of code to SQL and SQL to code generators as generalized techniques, but I've not used SQL to code generators because these are not practical for most teams in the domain spaces where I operate.
Your original quote, verbatim:
> Eg compare to strongly-typed query generators
"strongly-typed query generators" not "strongly-typed command generators" nor "strongly-typed code generators".
EF is precisely a code to structured query language (SQL) query generator and not a query to code generator.
.NET is a fantastic ecosystem. Has a decent build and dependency system (NuGet, dotnet run/build, declarative builds in XML). Massive standard library, with a consistent and wide focus on correctness, ergonomics, and performance across the board.
You can write everything in many languages, all on the same runtime: business logic in C#; hot paths interfacing with native libraries in C++/CLI; shell wrappers in PowerShell, document attachments with VB, data pipelines in F#.
I feel more people should use it, or at least try it, but sadly it is saddled with the perception that it is Windows-only, which hasn't been true for a decade (also, IMO, not necessarily a negative, because Windows is a decent OS, sue me).
> but sadly it is saddled with the perception that it is Windows-only, which hasn't been true for a decade
In my experience it does not work very well outside of the sanctioned Linux distributions. Quirky heisenbugs and nonsensical crashes made it virtually unusable for me on Void. I doubt that's changed in the years that have since passed.
> not necessarily a negative, because Windows is a decent OS
Is a language runtime worth an operating system? I think that's a paradigm we left behind in the 1970s when the two were effectively inseperable (and interwoven with hardware!) I wouldn't expect someone to swap to using a Unix system because they really want a better Haskell experience.
I just don't see any actual interesting or meaningful reasons to care about .NET, I effectively feel the same way about it that I do about Go. Just not something that solves any problem I have, and doesn't have anything that interests me. Although effectively I did try it, so it's a moot point considering that's one of the outcomes you're wishing for.

It's open source. Did you follow the spirit of Linux to file a bug report of as much sense of the crashes as you could make? Most OSS only supports as many distros as people are willing to test and file accurate bug reports (and/or scratch the itch themselves and solve it). It seems a bit unfair to expect .NET to magically have a test matrix including every possible distro when almost nothing else does. (It's what keeps distro maintainers employed, testing other people's apps, too.)
It probably has gotten better since then, for what it is worth. .NET has gotten a lot of hardening on Linux and a lot of companies are relying on Linux servers for .NET apps now.
At the very least there are very tiny Alpine-based containers that run .NET considerably well and are very well tested, so Docker is always a strong option for .NET today no matter what Linux distro you want on the "bare metal" running Docker.
> Most OSS only supports as many distros as people are willing to test
Linux distros don't differ too significantly from each other nowadays (systemd plus a different package manager most of the time), so I'm almost sure this is not the source of problems.
Nonetheless, I can only add that we have ridiculous slowdowns in some standard library network calls on Linux, and at that point it is just not true that it will "seamlessly run on Linux", unfortunately.
> Did you follow the spirit of Linux to file a bug report of as much sense of the crashes as you could make?
No, because the only reason I needed C#/.NET to work was to use an internal tool someone before me had written in C#/.NET. It was not really to explore C# or make it usable. I just threw out the old tool, wrote a new one in scheme so I could do my job, and moved on with my life. I don't particularly care about this spirit of Linux, and Microsoft's tooling being weirdly fragile isn't my problem. I assume they already know this is an architectural issue, hence why they specify supported distributions. On principle I believe solving the architectural issue is what they should be concerned about, rather than making new bandaids.
> Most OSS only supports as many distros as people are willing to test and file accurate bug reports
The problem is that most runtimes and standard libraries don't need to specify a notion of a "supported" distribution. At best, they just refer to platforms with pre-made packages while happily pointing other distributions to the git repo. Even complicated, highly abstract and weird ones don't make this kind of distinction. SWI-Prolog and its myriad of frameworks (which includes a full blown GNU Emacs clone) work out of the box anywhere. GHC and the RTS work flawlessly out of the box.
I understand (even if I don't feel the same way) why a comprehensive abstraction layer like .NET is evangelized. All the same I have to consider that it's a product of a multi-trillion dollar corporation, made to compete with the thing whose marketing tagline is "write once, run anywhere". That only makes the distro dependency stand in an even harsher relief, frankly.
You like .NET? Perfectly fine and valid, and I assume it actually works for you. Just indicating that "cross platform" is contingent on more than kernel and cpu architecture here, which is fairly unusual for this type of software. That's before we get into things like comparisons with ocaml, which I know is miserable on Windows and thus is often considered not really something you'd seriously consider using there. The .NET ecosystem essentially has the same problem outside of Windows where the grain and expectations of the tooling are counter-intuitive to the operating system and usual modus operandi of its users.
I think there is an architectural problem, but not where you seem to be expecting it to be. I got caught up in some low level distro nonsense+drama from smashing my head against horrors deep in autoconf in automake and got a deep look into the realm of the Distribution Maintainer lifestyle and how much Linux distributions are individual snowflakes despite presumably all being the same OS. As the old joke goes "the only stable ABI on Linux is Win32".
.NET has a huge kitchen sink standard library. Maybe the closer parallel is Python and Python has had periods where it only supported a few named distributions, too. That's not currently the case, but "how the sausage is made" is still a lot grosser than you might expect, with some Distribution Maintainers maintaining entire forks and a lot of the work not done by Python directly. Python is everywhere because it became one of the favorite shell scripting languages of Distribution Maintainers. (Which also exacerbated the Python 2 to 3 migration because entire distros got stuck on 2 while all their shell scripts got rewritten.) (But also if you want to compare Java's cross platform to .NET's I think we need a long digression into how many Java runtimes there are and the strange and subtle incompatibilities of different distro's affiliations to one or another. I also made the mistake of trying to use a Java application as a regular application in my youth of accidentally dealing with deep distro incompatibilities. That was also not fun.)
I get it, you don't have to like .NET. I just think you have an inflated view of what "cross platform" means when it comes to Linux. Linux isn't just one platform. Most things are rebuilt from source constantly because the binary interfaces especially libc's/glibc's under them are constantly shifting like quicksand. See also the messes that are Flatpak and Snap and how much work they've done to try to build around distro incompatibilities (by building increasingly more complex wish-it-were-VMs).
I work with C#/NuGet on windows every day and my experience is entirely the opposite.
The build and dependency systems are an abysmal esoteric, poorly documented mix between csproj files, sln files, random scattered json files, etc.
The standard library in my experience sucks and has all sorts of issues, especially around Uris, DateTimes, etc.
And the ecosystem itself has such a low quality bar, ironically _especially_ with anything made by microsoft. For every nuget package that's well-designed, well-documented, and easy-to-use, there's five which have bugs and undocumented exceptions and poorly-designed APIs.
If you work with old .NET Framework, then maybe I would agree. What kind of issues do you have in standard library or how they are only biting you? Nothing is perfect, but compared to other (popular) alternatives, C#/.NET is the best you can get today.
Why is the ecosystem bad? I haven't ran any .net code on anything but Linux in years. The open source community is great. I don't know why it gets a bad rep.
Or is it becoming a ball-of-mud/bad language compared to its contemporaries?
(Honest questions. I have never used .NET much. I'm curious)
