code-debug VS free-vscode-csharp

We will use dap-mode with the dap-gdb-lldb option here. Under the hood, it uses the debug adapter from the Native Debug VSCode extension. Configuring it is described on the dap-mode webpages. After we have configured dap-mode, we could in theory reuse the launch.json configurations from the VSCode related articles above. That will require that you also use lsp-mode, as dap-launch depends on the lsp-workspace-root function and will not resolve when lsp-mode is not used. I don't use lsp-mode with C (company-clang and company-c-headers provide what I need), so the next logical solution would be to create a debug template ourselves:

I'm not sure.

I can see that this extension claims to make debugging with GDB work in VS Code:

https://github.com/WebFreak001/code-debug

and that at least for emacs there exists a project to use that extension:

https://github.com/emacs-lsp/dap-mode/blob/master/dap-gdb-ll...

Not having tried it, I can't speak to how well it works, and I don't know if there are adapters for other editors.

The link at the top of page here, references the github repo : https://github.com/WebFreak001/code-debug which isnt the same thing as installed by vscode or by running dap-gdb-lldb-setup . Indeed this link points to a codebase using .ts files in different locations to the VSCode extension installed .js files. (I did set up the dap program/path variables to use the .ts files but that didnt work)

I only tried F# for few days, but it was a pleasant experience on both macos and linux.

dotnet CLI should take care of build process, it can even generate self-sufficient executable (that bundle parts of .NET in them). The infamous required XML boilerplate has also been cut down to near-zero.

My biggest gripe is that Microsoft's debugger is closed-source and proprietary (though free for users of official VSCode builds). There is open-source netcoredbg by Samsung, so you can use VSCod[e,ium] with https://open-vsx.org/extension/muhammad-sammy/csharp , but YMMV.

When looking into C# tools though, my understanding is that the main debugging tool is under a proprietary MS license, although maybe I'm misunderstanding that. My question is, is there a FOSS debugger or tool kit for C# development? I did find this on the marketplace but am not sure if this is what I'm looking for. I know this is a bit of a niche case but was hoping to clarify. I'm not committed to VSCodium and am open to other text editors/IDEs, although would prefer to stick with it if possible.

My understanding is that I can install VSCodium and that they have many of the most popular extensions available. They even seem to have an alternative for the C# debugger. I could also use VSCodium and manually install the Microsoft extensions from the distributed VSX files.

and there is a VSCode extension that uses this instead of the MS debugger

https://open-vsx.org/extension/muhammad-sammy/csharp

C# language (powered by OmniSharp): Official C# language support. The extension is subject to this restrictive license because it uses Microsoft's proprietary debugger. The source code is available under a MIT license. See this comment in the C# extension repo for some discussion on this. There is an alternative version of the C# extension in the Open VSX Registry that uses Samsung’s MIT-licensed Debugger.

Yeah, Gitpod is pretty nice for what it is. Although it's worth mentioning that certain proprietary Microsoft extensions are licensed for use only in Microsoft distributions of VSCode, so they won't work in Gitpod. Most extensions do work, but Pylance, C#, C/C++ doesn't, to name a few exceptions. Although for C# there is a FOSS extension you can use instead and for C/C++ there is clangd.

I'm not very familiar with C# and .NET, so I can't help you with any specifics. But I do know that Microsoft actively prevent the usage of their proprietary extensions such as the one for C# in non-Microsoft distributions of VS Code, such as VSCodium. Although if you're using VSCodium, you've probably installed the alternative FOSS version of the C# extension, unless you've sideloaded the official C# extension?

For C# there is https://github.com/muhammadsammy/free-omnisharp-vscode for Python there is https://github.com/Microsoft/pyright (Pylance is the proprietary counterpart) for C++ there is https://github.com/clangd/vscode-clangd

If you want to stay FOSS, you can use this fork of the C# plugin which uses a free debugger: https://github.com/muhammadsammy/free-omnisharp-vscode

The download URL for the debugger seems to have changed, but the latest version of the extension should include a fix for that (see muhammadsammy/free-omnisharp-vscode#20).
