Tamir Dresher presents debugging tricks and techniques for software developers. The presentation covers setting breakpoints, comparing objects while debugging, handling exceptions, debugging multithreaded applications, post-mortem debugging using dumps, and debugging LINQ queries. Attendees are encouraged to try the open source OzCode debugger, which provides additional features to aid the debugging process. Contact information is provided for any questions.

- 4. Agenda Breakpoints Comparing object while debugging Exceptions Debugging Multithreaded Applications Post-mortum debugging Debugging LINQ 4
- 7. Method Breakpoints If you type a method name (without class name) VS select all that matches 7
- 9. Conditional Breakpoints (OzCode) 9 invoice.Id915486 intinvoice.Id915486 int
- 11. Make object ID The object is later available in every watch window 11
- 13. Exception 13
- 14. First Chance Exceptions Breaking when thrown OzCode makes it easier 14
- 17. Staying on the same thread (freezing other threads) 17
- 18. Tracepoints (VS) a.k.a Printf(…) debugging 18
- 21. Finding Tasks Deadlocks Debug –> windows –> Tasks 21
- 23. Automatic Dump Creation To enable it, set the reg key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsWindows Error ReportingLocalDumps DumpFolder – Location for the output dumps DumpCount – Maximum amount of dumps in the folder DumpType 1 – Mini Dump 2 – Full Dump 0 – Custom Dump CustomDumpFlags – if DumpType is 0, set the dump options 23

Editor's Notes
- #4: My name is tamir dresher Im an architect from codevalue israel and a software engineering lecturer at the ruppin academic center CodeValue is a consulting company and we are also the proud development center of OzCode the amazing debugging extension for visual studio. We have a booth here at conference, so please go and check it out, youll be amazed how you lived without it. My book Rx in action is now available at Manning early access program should be published in the next few months. And that the end of my self promotion(it never hurts right?). So what are we really here for?
- #5: Breakpoints conditional breakpoints Comparing object while debugging Object IDs OzCode Compare Exceptions Breaking on exceptions Conditional exceptions break Debugging Multithreaded Applications Freezing debugging to the current thread detecting deadlocked tasks Using tracepoints Finding an object and seeing all object of certain type while debugging Debugging LINQ Post-mortum debugging Dumps
- #31: items.Where(i=>i.tags.Contains(“swift”)).ToList()
