I use Visual Studio daily, and Claude Code only ships native integration for VS Code (annoying). So, I built the Visual Studio half myself. It s an unofficial extension that speaks Claude Code s undocumented IDE protocol.It started simple. Review Claude s edits in the real VS diff and accept or reject there, with no duplicate y/n prompt in the terminal, plus sharing the C# and C++ compiler errors with it directly.The infra I built for the extension allowed me to add the interesting part, the VS debugger. When you re paused at a breakpoint, Claude can read the call stack and locals, and with a toggle it can drive the debugger itself: set breakpoints, step, start and stop a session, and find a bug by running the code instead of reading it.There s a short walkthrough in the README where it catches a bug that never shows up in the output, by watching a counter fail to reset as it steps through a loop.Would really appreciate if you take the time to check it out. Thanks!
