Become a PowerShell Debugging Ninja
summary
Lots of concrete debugging moves and the exact tooling to try them: inspect $Error (he primes it with 20 errors), use Format-List -Force to reveal Exception and InnerException, group/sort $Error to find the most common or first error, wrap functions in try/catch and rethrow with the caller’s ErrorActionPreference preserved, set conditional breakpoints with set-PSBreakpoint, use wait-debugger / debug job / enter-pshostprocess for remote runspaces, and install debugpx for niceties that actually work in demos.
