It's very frustrating having all of these tools only support Windows.
Despite all the wonderful work Microsoft has done with CoreCLR, the "IDE" debugger is still only available under a license that only permits use with Visual Studio and VSCode [1] and mdbg is still nowhere to be found for CoreCLR [2].
From what I've gathered, the best you have right now for doing command line debugging is the "SOS" plugin for lldb, which seems to require building the lldb plugin and sometimes even lldb (!!) yourself [3][4].
The “IDE” debugging library fuss was mistaken. CoreCLR supports the same COM ICorDebug API as mainstream .NET but Microsoft have their own private C# bindings library for using it with VS/VSCode. Anybody can generate their own C# bindings, JetBrains already did.
I say this as someone who was using ICorDebug 13 years ago.
No mention of the excellent LINQPad[1] or ilspy[2]? Both do decompilation, I use LINQPad a lot for quick sanity checks, although it's intended for database work I rarely actually use it for that. It'll also spit out IL code and expression trees.
ILSpy is a lightweight decompiler that you can just drop DLL files into to see their code. It has some nice analysis tools that allow you to find references and implementations. I associated .dll files with it so they open in ILSpy by default.
You can plug Reflexil [0] into ILSpy for on-the-fly code patching. Then once you've got something going, you can (manually) port your changes over to a Mono.Cecil-based [1] patching program. This is how I hack up Unity games written with C#.

Not very fun if you're not using Windows.
