Advanced .NET Debugging: Addison-Wesley Microsoft Technology

Autor Mario Hewardt Patrick Dussud
en Limba Engleză Paperback – noi 2009
The Only Complete, Practical Guide to Fixing the Toughest .NET Software Bugs
Advanced .NET Debugging is the first focused, pragmatic guide to tracking down today's most complex and challenging .NET application bugs.
Authored by Mario Hewardt, coauthor of the widely praised Advanced Windows Debugging, this is the only book to focus entirely on .NET's powerful native debugging tools, including WinDBG, NTSD and CDB. Using these tools, Hewardt shows how to identify the real root causes of problems--far more quickly than you ever could with visual debuggers.
Hewardt first introduces the key concepts experienced .NET developers, testers, and support professionals need to successfully use .NET's native debuggers. Next, he turns to sophisticated debugging techniques, using real-world examples that demonstrate many common C# programming errors. In particular, he presents the most thorough and useful guide to .NET memory debugging ever published.
Advanced .NET Debugging also offers detailed, practical coverage of postmortem debugging; the use of PowerDBG and other "power tools"; and, finally, the debugging implications of the new .NET CLR 4.0.
This book enables you to
  • Master and successfully use Debugger Tools for Windows, SOS, SOSEX, CLR Profiler, and other powerful tools
  • Go beyond code reviews and tracing to identify root causes more quickly and accurately
  • Debug live machines with zero footprint and no configuration changes
  • Streamline and accelerate QA testing
  • Support production customers using static snapshots, not live processes
  • Perform key tasks such as examining thread-specific data, the garbage collector heap, and .NET exceptions
  • Troubleshoot complex .NET assembly dependencies
  • Solve difficult synchronization problems, including deadlocks and thread pool problems
  • Track down problems with Platform Invocation and COM Interoperability
  • Generate and successfully analyze crash dumps
  • Gain a deeper, more practical understanding of the .NET runtime and its components
This book is a must-have for experienced .NET developers, QA specialists, product support engineers, and for operations engineers who maintain "cloud"-based .NET software.

Descriere

“Mario Hewardt’s Advanced .NET Debugging is an excellent resource for both beginner and experienced developers working with .NET. The book is also packed with many debugging tips and discussions of CLR internals, which will benefit developers architecting software.”
–Jeffrey Richter, consultant, trainer, and author at Wintellect
 
“Mario has done it again. His Advanced Windows Debugging (coauthored with Daniel Pravat) is an invaluable resource for native code debugging, and Advanced .NET Debugging achieves the same quality, clarity, and breadth to make it just as invaluable for .NET debugging.”
–Mark Russinovich, Technical Fellow, Microsoft Corporation

Recenzii

Praise for Advanced .NET Debugging
 
“While the .NET environment provides a developer with a powerful toolbox to accomplish their goals, it can often be a daunting task to debug some of the issues that inevitably crop up during software development. This book provides the crucial details about how the CLR works internally, which you need to know to diagnose many classes of bugs in your .NET programs, and it provides clear examples of how to solve the same types of issues we see our customers struggle with on a daily basis. This book is required reading for all serious .NET developers.”
—Lee Culver, CLR Quick Response Team, Microsoft Corporation
 
“Have you ever wondered why your .NET application is not responding? Or why it’s intermittently consuming high CPU? Or crashing? When things go wrong you need to think low level, using the proper knowledge and tools to investigate the internals of your application. Advanced .NET Debugging delivers the knowledge necessary to quickly isolate nasty software problems. Welcome to the debugging world!”
—Roberto A. Farah, Senior Premier Field Engineer, Microsoft Corporation
 
“Mario Hewardt’s Advanced .NET Debugging is an excellent resource for both beginner and experienced developers working with .NET. The book is also packed with many debugging tips and discussions of CLR internals that will benefit developers architecting software. I highly recommend Mario’s book.”
—Jeffrey Richter, consultant, trainer, and author at Wintellect
 
“This book talks about tools such as SOS in the kind of depth that I have not seen elsewhere. It’s a definite aid in understanding and debugging managed application behavior.”
—Maoni Stephens, GC Developer, Microsoft Corporation
 
Advanced .NET Debugging is essential reading for someone who wants to get under the covers and obtain an intimate understanding of how the .NET Common Language Runtime works. It clearly identifies the layout of the system and how the assemblies are loaded and organized. I recommend it to anyone who wants to debug more complex issues brought on by synchronization problems and corruption. It also effectively addresses the difficult task of postmortem debugging.”
—Pat Styles, Microsoft Corporation
