You should try Jetbrains Goland if you're looking for a modern IDE with a great debugging experience [0]. If you're talking about visual studio being modern, i don't think that's true. I have used it recently and i was surprised by how outdated it is (maybe i'm not used to it). Also, I can't seem to do any changes while the code is running. That's very annoying.
