netcoredbg VS MonoDevelop

Open source. OP is referencing a decision Microsoft made last year to include some closed-source components, in particular the debugger from Visual Studio, in the default C# extension for Visual Studio Code. There is a Samsung-provided open source debugger available if you absolutely require it, but the closed source stuff doesn't have any usage restrictions afaik.

idk what SOS is, but here is netcoredbg, and it works decently (I use it myself)

If you want to debug C# from Emacs, it’s the only choice AFAIK.

Or use CLi debugger on Linux server itself, I haven't used this one. https://github.com/Samsung/netcoredbg.

There is also this debugger developed by Samsung: https://github.com/Samsung/netcoredbg

An older version of the underlying source code remains available: https://github.com/mono/monodevelop

From what I understand MonoDevelop has been discontinued. Even their repo has been archived.

SharpDevelop and MonoDevelop are both dead and focused for devs which gives them different priority than apps targeted at non-devs, but they show how to put together seriously complex apps, and they're the ancestor of the Visual Studio for Mac.

Monodevelop

There are Linux binaries for MonoDevelop which is what VS for Mac is based on.

Using Visual Studio with Wine is not really possible. But you have other IDEs as options. You can pack Visual Studio Code with the needed plugins. You can use MonoDevelop which is the IDE from the Mono project https://www.monodevelop.com/. Something to add here, the Mono project is actually developed by Microsoft. And there is Jetbrains Rider, I personally use it every day at work and am kind of in love, but it costs you 139 € in the first year.
