Accelerated .NET Memory Dump Analysis
Accelerated .NET Memory Dump Analysis
Training Course Transcript and WinDbg Practice Exercises, Third Edition
About the Book
The full transcript of Software Diagnostics Services training with 13 step-by-step exercises, notes, source code of specially created modelling applications and selected Q&A. Covers 22 .NET memory dump analysis patterns plus additional 11 unmanaged patterns. Learn how to analyse CLR 4 .NET application and service crashes and freezes, navigate through memory dump space (managed and unmanaged code) and diagnose corruption, leaks, CPU spikes, blocked threads, deadlocks, wait chains, resource contention, and much more. The training consists of practical step-by-step exercises using Microsoft WinDbg debugger to diagnose patterns in 64-bit and 32-bit process memory dumps. The training uses a unique and innovative pattern-oriented analysis approach to speed up the learning curve. The third edition was fully reworked to use the latest WinDbg version and Windows 10. It also includes 9 optional legacy exercises from the previous editions covering CLR 2 and 4, Windows Vista and Windows 7. Prerequisites: Basic .NET programming and debugging. Audience: Software technical support and escalation engineers, system administrators, DevOps, performance and reliability engineers, software developers and quality assurance engineers.

C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.
The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.
