We had a tiny coding project at work last week, and one part of it kind of struck me.

My coworker's half of the project was to show the user a simple form where they would input two lines text and click the "submit" button. It would then write that info to a text file and launch my half.

My half of the project took that data, stuffed it into the middle of some XML, then launched the newly-created file.

Try to guess the spoiler. My coworker's half was eighty thousand times (160 MB vs. 2 kB) as large as mine. Is there an equivalent to "What Intel giveth, Microsoft taketh away" for harddrive space?

Not judging, just curious: Why was this a two-man project?

I'm not actually a programmer, and learning how to work with Windows to build a UI would be a long and annoying process relative to delegating it. On the other hand, I had already set up a script for more complex control of the laser, so creating a stripped down version was easy.

The project took me about three hours between writing my part, delegating the other, and testing them both together.

.NET?

I think so, but I wasn't involved in that half beyond providing the specs and testing it.

Yeah 160mb is insane, I've seen very few apps that large. Front-end frameworks can be nasty.

The default settings for almost any .NET Core gui (WinForm or WPF) app will give you ~120mb+ files, and a mess of them. Bundling almost the whole runtime into each deployment is supposed to avoid the pain of a separate runtime installation, but it's a messy tradeoff either way.

There's an 'app trimming' config that tries to reduce bloat a bit. It's kinda annoying and doesn't do a great job even in the best-case scenarios, though.. Unfortunately, one of the better arguments for sticking with .NET Framework, especially if considering mass deployment -- if you can get away with .NET Framework 4.x- or earlier features, Win10 and Win11 have it included by default and still leave (admittedly bulkier-than-necessary) <10MB executable.

If you're just deploying to Windows machines, it's genuinely not hard to use newer .NET versions to produce that <10MB GUI binaries most of the time:

  • If you know your deployment runtime (for .NET Desktop, win-x86, win-x64, or win-arm64), in modern versions of .NET you can just dotnet publish -r <runtime> and it skips the default runtime bloat. Of course, you now have to deploy the right binary to your user, but this isn't hard in 2024 - Windows on ARM is basically a fantasy, W11 doesn't even have an x86 version any more, and W10 is going out of support next year (whether you like it or not - RIP).
  • You don't have to bundle the runtime with your application. For the minor annoyance of adding some extra code to your installer bundle to download and execute the runtime installer when the runtime is absent, you can convincingly gaslight your users into thinking your application is just the tiny binary, and the runtime library is just some weird Windows thing that came along for the ride. And this is basically what you had to do with Visual C++ Runtimes, so it's not like the users haven't been doing this for years...

I guess if you're optimizing for binary size, you're never gonna beat Microsoft bundling the .NET Framework binaries directly into every Windows distribution for you. But if you can, come join us in the future! I uplifted a .NET Framework 4.5 application to .NET 8.0 Desktop with about 10 lines of inconsequential code changes and some project file hackery, then attached new pieces to the project using abstract static interfaces and generic math only available in .NET 7 or greater, and added a few lines of code to a bundled installer to download the runtime from Microsoft. It all just works, it's about 20% faster on the critical path, my binary size went from 1MB to about 1.5MB, and it took me a day instead of a month to add the new feature I needed. It's great.

I won't claim there's no reason to use .NET Framework any more (particularly if you committed crimes against humanity with AppDomains), but the happy path for most new GUI development in C# targeting Windows should point you squarely at .NET Desktop on the most modern version of .NET LTS (the even-numbered ones). It's infinitely more tolerable than the other garbage desktop front-end frameworks excreted and subsequently rug-pulled a year or two later by Microsoft in the last few years (UWP, MAUI, WinUI x where {xN, x < ∞}), it's not a website and some WASM in a trenchcoat (Blazor, ElectronNET), and you still get all the WPF goodness (and WinForms, if you really want it).

Ah, I stand corrected then. Last time I tried was early in the .NET Core 5 days, and turning off everything but x86_64 and using aggressive trimming still left >30MB deployments for some of the common projects I was working with at the time. They were admittedly weird in ways I can see the linker panicking about, but they weren't that weird. Will have to try it out again.

Yeah, if you're doing anything even moderately performance-, security-, or complexity-dependent, Desktop or Core make a lot more sense. It's mostly light apps like the 'write data from interface to text file' or your standard CRUD that a lot of the bennies just aren't going to come up.

((And I'll admit I've abused the fuck out of AppDomain.UnhandledException, given how hard it is to get error reports with actual details from Microsoft.))

It's infinitely more tolerable than the other garbage desktop front-end frameworks excreted and subsequently rug-pulled a year or two later by Microsoft in the last few years (UWP, MAUI, WinUI x where {x ∈ N, x < ∞}), it's not a website and some WASM in a trenchcoat (Blazor, ElectronNET), and you still get all the WPF goodness (and WinForms, if you really want it).

Definitely agreed there. For simple GUI applications, the .NET ecosystem as a whole is just incredibly convenient. Even looking at competitors outside of Microsoft, it's vastly more convenient than trying to fight with JavaFX or Swing for almost every case excepting where absolutely need (reliable) Linux support (and I'd be tempted to say fuck it and try mono even there), it's a lot more robust that using JS and pretending your web browser is a reliable application, and the less said about QT the better.

It's not .NET problem per se, modern .NET can trim the assembly very well. Sounds like they used some GUI framework that is a browser in disguise, like Electron.

Incidentally, you can use Electron.NET with .NET Core and get the "best" of both worlds. The .NET portion is tiny, but the electron portion is basically guaranteed to be over 100MB, full of front-end razor template/css hell, oodles of extra javascript to do all the things that aren't natively supported correctly, squeeze your entire UI update logic through a SignalR straw, and an infinite menagerie of implementation bugs and issues. But it'll run on just about anything, including a browser. And the ASP.NET side is pleasant to work with.
