Take your PowerShell to the next level with error handling and debugging
summary
Demos show how PowerShell actually surfaces errors: exploring $Error and $ErrorView modes, using $? and $ErrorActionPreference to turn non‑terminating failures into error action stop, and choosing between throw and Write-Error. Examples include catching specific exception types, collecting per‑item failures, and a live VSCode debugging session with breakpoints and step into of a module that gets fixed on the spot, proving the techniques work end‑to‑end.
