I agree, however most indies don't need them, and most pros are getting into Unreal instead.

Also something like Burst is a workaround for using Mono with C#, which gets solved in Godot with C++.

How's the whole DOTS adoption going?

The biggest issue is missing plugins, but they have an extension point to add them.

Naturally they expect them to be written in Rust, which might be an issue for some then again Vite folks are also going into RIR.

Well, your employers are the opinion language sugar doesn't matter in the CoPilot agentic world, so there is that.

As such my opinion remains that in such context saving keystrokes isn't that high priority, when agents do the actual work.

Thanks for replying, though.

Unfortunately the way they managed to stick with MonoRuntime and Burst, kind of made more harm than good, regarding C# adoption on the games industry.

Many issues people associate with C#, are actually only relevant in Unity, because of this.

OS APIs for one, at least there are some Win32 calls that take unions if I remember correctly.

One of the reasons .NET had Managed C++, replaced by C++/CLI (nowadays C++20 compliant, minus modules), is exactly that P/Invoke (and RCW/CCW) cannot represent everything.

Which they don't want to expose on .NET type system directly.

That soon is like a decade in the making.

And with many folks going into alternatives like Godot, it means C# ends up losing the mindshare it got.

Yes, you can use C# with Godot, but most folks end up with GDScript, or GDextension.

Apparently most folks were happy enough with XCode and didn't bother to buy AppCode licenses, hence why JetBrains gave up on it.

Yes, provided you are running vim on macOS, and calling into the xcode command line tooling.

Some interesting stuff you will get out of Dr. Dobbs articles, as someone that was an avid reader.

- The Small C compiler set of articles, where you will get the sense not even K&R C was used outside UNIX for quite some time, only a common subset.

- The toolbox articles creating a Turbo Vision like framework in Object Pascal

- The evolution of Python and related adoption

- Strange programing languages like Actor, C@+ (try to search this one nowadays), Sather, BETA

- The fashionable compiler benchmarks that used to be quite common back in the day

- The evolution of C and C++ at ISO, while their standards were being started

- A more heterogenous way of software development, when it wasn't only UNIX clones and Windows.

C# only exists because Sun did not allow Microsoft to keep using J++.

Without the lawsuit, COM+ Runtime (aka .NET) would have used J++, as originally designed in the Ext-VOS paper.

Ah, but because they have to keep everyone happy, you can choose between var or new(), and then we need to teach both to juniors.

I equate this language addition to the same mistake that !! was going to be a few years ago, until it got all that discussion threads on Twitter.

C# doesn't need to have syntax sugar for every possible use case.

Some of the more recent features feel like the outcome of the team pressure to have new language features to announce in November every year.

I think they now have an issue getting new language features every year, this is how it comes to be.

Many systems programming languages with GC have existed since the 1970's, we don't seem most adoption mostly due to developer culture, and monetary issues with management.

dynamic was also added as part of DLR, initially designed for IronPython and IronRuby support.

This inspired the invokedynamic bytecode in the JVM, which has brought many benefits and much more use than the original .NET features, e.g. how lambdas get generated.

ML-style discriminated unions, actually.
