summary

Memory-dump debugging solves crashes, hangs, leaks and perf blips by showing the actual failing exception, roots and heap growth. Reproduced examples: an ArgumentOutOfRangeException crash exposed by loading SOS and using dumpheap -stat and gcroot; a low-CPU hang where eight threads sit in GetAllProducts discovered via Visual Studio/parallel stacks; a leak of 31,000 NewsController instances (~368 MB) traced to a cache callback. Tools and commands shown include ProcDump -ma, WinDbg/SOS, Visual Studio dumps, DebugDiag reports and automatable CLRMD scripts.
