“CLR version 1.1 (Everett) debuts a set of debug probes that enable you to find and diagnose difficult bugs, even in a production environment. CLR SPY is a C# Windows Forms program that exposes these probes in a simple UI, so you can find your bugs before others do! The tool lets you easily configure all 11 probes, categorized as error probes (which can provoke debug breaks), warning probes, info probes, and probes that force nondeterministic failures to occur.” [via Ido Samuelson]
