Hi Lemmings, I wondered if anyone had successfully created a C# project that uses winforms on linux.
I just can't figure out how to do it.
I use Arch and have full dotnet 6 and 8 packages; but I can't dotnet new winforms as the template seems to not exist.
I also have installed mono and monodevelop installed, but even the simplest solution (Console App) can't load correctly (currently I have /usr/share/dotnet/sdk/8.0.102/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.DefaultItems.Shared.targets(152,5) : error MSB4062: The "CheckForImplicitPackageReferenceOverrides" task could not be loaded from the assembly /usr/share/dotnet/sdk/8.0.102/Sdks/Microsoft.NET.Sdk/targets/../tools/net472/Microsoft.NET.Build.Tasks.dll. Invalid Image Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. but there were different similar errors before, these errors.
I don't really want to boot up a VM every time I have to code on that project, but I'm starting to feel desperate about this.

TLDR: How does one create and work on a WinForms C# project with linux ? Any suggestions are welcome

Some clarifications for future readers :

  • It is for a school group project; winforms in imposed, which sadly won't let me go with Avalonia

OP,

Here's a friendly reminder that programming.dev has a community dedicated to .NET: !dotnet@programming.dev

Ah! thank you for pointing that out !

This isn't an answer to your question.

I'm just curious, why winforms? Is there something that they do really well that you're just dying to use on Linux? Trying to get a legacy application working? Familiarity?

[-] nope@jlai.lu 2 points 6 months ago

none of that; it's a school project which imposed winforms, else I'd have found some thing that would have worked for my linux

[-] Dark_Arc@social.packetloss.gg 2 points 6 months ago

I'd recommend using a VM in that case and calling it a day.

That syllabus likely assumes Windows. C# on non-Windows is not impossible, but it's going to require effort infeasible for school projects like that one. As you're facing it, C#'s packages were originally not meant to be used cross-platform, and god only knows the amount of problems that lie ahead. That clearly didn't occur to the teacher's head while they designed the course.

You mean winforms (The windows specific UI) on non-Windows? Otherwise this is incredibly misleading, and plain wrong.

C# in non windows is the norm, the default even, these days. I build, compile, and run, my C# applications in linux , and have been for the last 5+ years.

[-] eveninghere@beehaw.org -1 points 6 months ago* (last edited 6 months ago)

Not talking about winforms in that quoted part. I thought that was obvious.

I don't buy the second paragraph, especially as the phrasing is so loose it can mean anything.

Edit: overall I think this will result in a typical internet conversation that turns into "lmao that's the weakest argument I've ever seen!" "you're so pathetic!" etc. etc.

Dotnet core (now just dotnet) was a full rebuild of the framework specifically for cross platform support so they could get more enterprise cloud hosting on azure, running everything on Linux

Modern C# is built for first class Linux support for everything except UI

[-] eveninghere@beehaw.org 0 points 6 months ago* (last edited 6 months ago)

Nope. There are nuggets that lack ARM binaries, for example. And I've had enough troubles on macOS therefore.

[-] thepiguy@lemmy.ml 6 points 6 months ago

The closest I got was by just using avalonia. I had to use winforms for my uni and convincing my teachers to allow my team to use avalonia was not easy. Avalonia is not even remotely similar to winforms. You can try setting up a VM, but I understand that it is not a real solution. I found some docs for an old version of mono which referenced some of the winforms API, but I had no luck running it.

[-] nope@jlai.lu 2 points 6 months ago

Well, I might try my luck with convincing my teachers to let us use avalonia but I'm not sure it will oucome to anything good. At this point I might as well use a VM for this, as I already had a VM for SolidWorks set up.

[-] agressivelyPassive@feddit.de 6 points 6 months ago

The "Win" in Winforms stands for Windows, capital W. It's simply not available for Linux.

[-] cbarrick@lemmy.world 15 points 6 months ago

Mono has some docs that imply they have implemented WinForms on X11.

[-] breadsmasher@lemmy.world 10 points 6 months ago

From the FAQ

A small driver is required for each operating system supported. Currently we have drivers for: X Window System Win32 Window System macOS Window System

so I think you’re right

Official source (emphasis mine)

Welcome to the Desktop Guide for Windows Forms, a UI framework that creates rich desktop client apps for Windows.

[-] cbarrick@lemmy.world 1 points 6 months ago* (last edited 6 months ago)

Of course Microsoft implemented it "for Windows".

The Mono project implements many of the .Net APIs in a portable way for other operating systems, including an implementation of WinForms on X11.

OP specifically mentioned that they were using Mono.

[-] fuzzzerd@programming.dev 6 points 6 months ago

Check out Avalonia. It's like cross platform WPF. Not winforms, but still pretty good and easy to start with.

[-] JakenVeina@lemm.ee 5 points 6 months ago* (last edited 6 months ago)

I know folks in the C# Discord have talked about getting WinForms to work on Linux, you could post a question there. But unless you're specifically dealing with maintaining some legacy app, you should not be using WinForms, much less on Linux. Avalonia or Xamarin are definitely the way to go if you're making something new and want cross-platform desktop support.

Protip if you do go down that route: Tutorials tend to ignore the fact that you don't have to use XAML to make anything in these frameworks. You should. But if it's more comfortable for you to write WinForms-style imperative code that you're used to, you 100% can, the APIs are not significantly different.

[-] Curdie@lemmy.world 2 points 6 months ago

I can definitely Avalonia for cross platform UI. It's amazing.

[-] douglasg14b@programming.dev 4 points 6 months ago

.Net 8 will work on Linux just fine. But winforms will not, it's specifically a legacy windows-only UI framework.

You're going to have to jump through some incredible hoops to get it to work on Linux. Which are definitely not part of your normal curriculum.

[-] mvirts@lemmy.world 2 points 6 months ago

Maaaybe try an older visual studio install under wine?

[-] nope@jlai.lu 1 points 6 months ago

that could be a solution indeed, but I'm not sure the latest working version (2010) would have all the features that would fit my needs, see WIneHQ's rating history for Visual Studio

[-] Tramort@programming.dev 1 points 6 months ago* (last edited 6 months ago)

I know it's possible. I've used a keepass client on Linux that required Winforms; I think it was keepassx.

Mono was how I got it to work.

[-] nope@jlai.lu 1 points 6 months ago* (last edited 6 months ago)

well, mono in itself seems to work and I have successfully built the hello world winforms program using mono, but the monodevelop IDE won't seem to work at all, which would make coding harder than it should be.
I've also seen things online saying that monodevelop is half dead, so I don't have much hope about this

[-] Tramort@programming.dev 1 points 6 months ago

Does develop support mono? I have used kdevelop before and was really impressed by it
