I'm struggling to run Qt's C# examples because DotNet states that "Mono could not be found", yet DotNet Core is.

As reddit.com/user/rokejulianlockhart/comments/1ctpc4v states:

I'm attempting to run https://github.com/qt-labs/qtdotnet.git cloned using Gittyup, as https://github.com/qt-labs/qtdotnet/blob/b99c0857762db36dc10cb4d5bcea90128f044cc0/README.md#quick-start explains, using code-insiders-1.90.0-1715753654.el8.rpm on https://download.fedoraproject.org/pub/fedora/linux/releases/40/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-40-1.14.iso, but nothing seems to work:

1. Installed https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-dotnettools/vsextensions/csharp/2.30.24/vspackage?targetPlatform=linux-x64
2. Installed https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-dotnettools/vsextensions/csdevkit/1.6.6/vspackage?targetPlatform=linux-x64
3. Cloned https://github.com/qt-labs/qtdotnet.git.
4. Opened $HOME/Software/Git/GitHub.com/qtdotnet as a folder in VSCode.
5. The Dev Kit asked me to "upgrade" the folder, and linked to entirely irrelevant documentation not explaining what that means or how to accomplish it, but provided an alternative - choose the C# extension - so I chose that.
6. Was prompted to add missing files, so did so.
7. Was prompted to choose an .sln file, so chose one (one of the three without the third's "windows-" prefix, and which are labelled "DotNet 6" instead of windows-'s "DotNet 8", although I've both installed).

When I attempt to run it or, sometimes, perform one of those aforementioned actions, I am hit with a slew of strange errors - https://bugzilla.redhat.com/show_bug.cgi?id=2280895#c0 happened once, but usually, I'm informed that

Projects failed to load because the Mono could not be found. Ensure that Mono and MSBuild are installed, and check the logs for details.

or that msbuild has failed, which seems like it might relate to https://github.com/dotnet/vscode-csharp/issues/5476#issue-1467903164.

Where am I going wrong? I'm quite good at PowerShell, and want to learn Qt6, so this seems like the best way to go about it, but it's proving very difficult in comparison to how I recall using VS on Windows 10 two years ago being. However, I don't have a Windows machine or VM to test the repository on (I don't want to install VirtualBox and have a tained kernel).

Why not following the installation instructions on GitHub?
I did that. I've detailed that above. I even linked to them.

Then you have Visual Studio not VS Code (which means working on Windows).

I rather evidently don't, if I'm not using Windows. VS doesn't run on anything except an NT or Darwin base. However, I see why you're confused - it appears that I misread https://github.com/qt-labs/qtdotnet/blob/b99c0857762db36dc10cb4d5bcea90128f044cc0/README.md?plain=1#L45 as VSC, rather than just VS. How depressing - that'll be the cause of all this, then. Thanks.

My good advice, if you really want to learn "Qt".... Start to learn C++ instead of fiddeling around with Qt.NET bindings.

3. Cloned https://github.com/qt-labs/qtdotnet.git.
4. Opened $HOME/Software/Git/GitHub.com/qtdotnet as a folder in VSCode.

Why not following the installation instructions on GitHub?

1. Install requirements.
2. Clone repository
3. Open solution file qtdotnet.sln.
4. Press F5.

I don't want to learn a language that I won't want to use - I already know PyQt6 and PySide6 enough that I've been able to create what I want with them, but that means that every time I want to convert a CLI PowerShell script to having a GUI, I have to completely reinvent it in another language.

! Didn't know this abomination was a thing! What's next Qt for Rust, Ring, GO !?

ok, I give up.

@J-Hilk, well, Qt is pretty popular, for good reason. I'm as surprised as you are, though. XD

Yeah, but for the best "Qt" experience and to really learn how to use the Qt Framework (which is a C++ Framework), you should use C++.... or at least Qt for Python (via PySide/PyQt), which is reasonable as well...

Everything else (there might be people judging me on that), feels like "Oh Qt is great... so let's make it available for every other god damn platform/languague etc."
If I want to use Qt, I would go with C++/Python.
If I am somehow limited to C# (or some other language besides the two mentioned above), I would't consider using Qt... There might be easier/better alternatives, even though "Qt is great".

You said, you've "opened the folder" in VS Code... opening a directory is not the same as loading a project/solution file.

CLI PowerShell script to having a GUI

One guy here is the owner of some "Qt Widget CLI" project on GitHub... Which "renders" simple QtWidgets like buttons and so on, in a CLI environment.
Can't remember who is was actually :(
@kshegunov you (maybe)?
@J-Hilk or you?
@SGaist you know everything :P
Maybe one of you knows what I'm talking about and can link to that.

I've included six steps of what I did, and to my knowledge, I loaded it. Is VS Code incapable of that, even with the aforementioned extensions installed?

Thank you for that. I suppose a TUI isn't a terrible stopgap in some circumstances.
