A Lemmy post that contains a tweet that contains a Reddit comment. Quite a ride.

Well, like most people who haven’t used .NET, I have very strong opinions about it.

The first and main issue I take with it is how it’s all capitalised. Second but not less, it’s such a generic name. Am I gonna get websites in the .net domain or do I have to learn Google search beyond typing random junk, pressing enter, and hoping for a stackoverflow answer that works?

The things I bump in the most:

• Mutability. Everything is passed by ref so imutable and/or copy should be an important factor of the language, but it’s not. Struct vs class also was way to much impact but can both be used for an interface argument but have such different flow.
• Compatibility is always favored over improvement in the framework design and language. It has obvious pros as we need less porting, but newer functions in the language are often weird to work with and frameworks get replaced instead of improved, making the porting even harder.
• A lot of features work magically simple until you want some kind of custom behavior and they then become unmanageable complex. Like the default XML serializer where you can do no extension and everything can get serialized, or async function that abstract the threading untill you want to manage multiple parallel function with error checking and you get very weird and confusing code. Thay all work magically easy as long as you use them for nothing more difficult than the examples.

Threads like that twitter thread. Or to put it another way, the community and it’s single minded focus on everything Microsoft produces or endorses and nothing else is frequently off-putting to me.

I strongly believe there is no “best” in software, or maybe in anything. There is only “best” when you put it in context of your projects and constraints. .NET may very well come out on top in your context, it’s a solid ecosystem. LINQ is great, integration of major functionality comes out of one hand and often just works, you can hire from a large pool of candidates, performance is generally sufficent, I only hear great things from anyone who ever tries F#. The list goes on. I generally think the technology itself is a great general purpose choice and I’ve enjoyed writing C# for my job for a while, as well as for a few side projects.

But other things have other strengths. For one, the amount of open source library choices is much better. .NET is slowly growing on that front, but I’m still not convinced whether it will ever get to a level of JS or Java, despite sharing almost the same marketshare in case of Java. And frankly, that’s the community that breeds innovation. Lots of things are tried, very little sticks, but in the end you always have options. In .NET you don’t until Microsoft builds something for you.

Even Microsoft reconizes that:

There is a perception that other ecosystems (specifically Java, JavaScript, and Python) have more technological diversity and thus an overall stronger open source ecosystem. Historically, we’ve taught customers to expect all the features to come from Microsoft. Since we can’t build everything, especially not at a pace at which other OSS ecosystems evolve, the set of trusted libraries for .NET must grow beyond just Microsoft.

…

Getting critical adoption of this model in the .NET ecosystem will likely take years, but the goal for .NET 6 is to create the vision, get buy-in from the .NET Foundation and the open source community at large, as well as getting some of the fundamentals in-place.

(source: https://github.com/microsoft/dotnet/blob/main/docs/ecosystem-issues.md )

I am not convinced that this buy in from the open source community exists yet, in particular because Microsoft kept up their antics and showed their hand with things like the hot reload drama or shifting key parts of their products out of open source (pylance, the .NET debugger binaries, key parts of VScode are examples that come to mind).

And so .NET keeps taking on things that have been proven first elsewhere, behind the innovation curve. For example C# language features such as records or pattern matching. Or integrating open source technologies that become too big to ignore. Hello docker. Hello react integrations. Hello WSL. Hello functioning terminal in Windows, after having lived with the good old cmd for decades.

But until Microsoft officially starts endorsing and publishing things like that, it’s the worst in other languages when you ask the community. The truth is, other things have other strengths, but if you ask about LINQ and nameof() in Rust you will be disappointed. If you ask for a safe, performant alternative for embedded devices, it’s great (how is .NET doing on embedded ARM these days anyway?).

And maybe I’m making a problem where there is none. But I want to work with open minded people who focus on results, not tools based on some strange techno-religion. Unfortunately in .NET I often get that vibe. But to be entirely fair, I’ve also seen it in other places, like the functional world (Haskell, or Scala). And it’s slowly getting better in .NET with every integration. So not all hope is lost.

To be fair .NET is open source only recently and Avalonia UI is only catching up. More and more people will discover it eventually.

And Microsoft behaviour is also to be blamed. What is a free and full fledged IDE for .NET? VSCode comes close but is no match to VS.

And web bros will notice once Blazor hits on. It will though, right?

NuGet. The whole package management experience just feels so disjointed and tacked sometimes.

• VS package management is (search, upgrade) slow and buggy
• Central Package Management works for the CLI but is not implemented properly in VS, and is not available for Framework projects
• The Azure credential manager, for Azure based NuGet feeds, is hard to configure reliably
• Don’t even start me on issues querying / publishing NuGet packages via PowerShell

Type system rigidity, I started using TypeScript a lot over the last few years with FE work. TS is so much more flexible and expressive. I really wish that I could express constraints in C# as fluently as I can in TS

Enums really need more flexibility, unions, discriminated unions, left hand implicit type, better value support…etc

System.Text.Json still sucks, it’s not greedy, no global setting , non-sane default,no expando support…etc it’s awful to use.

Unstructured data in general is an absolute pain to work with.

Composability of tests is still super painful and verbose. Dynamic test generation is awkward and unergonomic. After doing testing and other languages that let you simply compose tests imperatively, C# testing is definitely painful.

IMHO C# is an acceptable language with an absolutely fantastic framework.

I love C#, but these are my primary gripes

I am a .NET dev and love the language, ecosystem, tooling and recently their open source initiatives. Few things that frustrate me. Here are my whines:

• Naming of framework — asp.net core / asp.net could have been one word say, Katana.
• Language features — I am still comfortable with C#6 or may be a few things from C#7. I know I do not have to use all new stuff, but I feel left out. Too much inertia as of now to get over the hump.
• I wanted to break into GUI stuff for long time, but there is no clear path. Avalonia is good and I hope the documentation becomes good as explained by Mike in a recent podcast.
• The company I work for has an initiative of OSP Open Source Practice. I feel bad that .NET/C# is not included in this ever. OSP only means Java, Python and probably Go. It is a nitpick, but MS has done so much to make .NET open source, yet even technology oriented companies think of MS development platform as a closed system.

When you have no ethics and just care about results you can also go fishing with dynamite…

That being said I didn’t know dotnet was now open source. So that’s a good point.

For me either:

• Versioning and naming. Framework 4.8.0 -> works down to Windows Server 2012; Framework 4.8.1 -> whoops you need Server 2021. Why.
• Bugs and regressions in its APIs and tools. Most are related to UI and accessibility as you probably guessed.
• VS. It has been slow and bug-ridden for a long time now, but just recently I hit that bug where searching text doesn’t find all places. I might have hit it before, but how would you know. It also feels like its tools are sometimes worse than in its previous versions. Suggestions got worse, for sure. But that might come down to my other points.
• Rather ad hoc, unfocussed language design and the problems that result. Better than many others, but still. Not learning (enough) from the past seems to be a common theme in PL design, but it sure doesn’t help that it isn’t an exact science.
• Anything UI.
