This is vsdbg (which comes with Visual Studio 2022 and the Microsoft-provided binary of VS Code).
There are alternatives like OmniSharp[1], the debugger shipped with JetBrains Rider, and Samsung's netcoredbg[2].

I've been using Omnisharp for ages, but I could never get netcoredbg working.
Last time I tried te integration with emacs-dap it kept segfaulting for no obvious reason.
But I may give it another try now!
