Building your own debugging toolbox with ClrMD
summary
Demo shows using ClrMD to load a 20GB memory dump, attach to live processes, and programmatically inspect heaps instead of typing SOS commands. Code enumerates heap object addresses to produce a grouped list of duplicate strings, and walks the TimerQueue linked list to count scheduled timers and read intervals. Toolchain uses Microsoft.Diagnostics.Runtime, a small WPF analyzer and a native WinDbg extension built via DllExport to expose managed helpers; the extensions run and return readable results in the demo.
