Linux and Winforms (jlai.lu)

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

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.

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