Visual Studio also does remote debugging, including for services running on Azure, and recently introduced across containers.

Usually the problema is that many developers never learned what a visual debugger is capable of, and the typical command line interface in UNIX leaves little room for exploration if people aren't curious to learn about them.

For example, many aren't aware that gdb has a TUI that eases the experience.

I know you can do remote debugging. I mean the case where you have a breakpoint in one service, and it calls to another service. You can't really "step into" that. Best you can do is connect to both services and have cooperating breakpoints.

But, really, this is something I've never actually done. Reasoning about how the system should behave has been enough to get me by.

A scenario I have used it a lot was in debugging cooperating processes in UNIX, a couple of years ago.

When some condition took place, the problematic process would break into the debugger, while the others would be parked waiting for me to attach to them.
