3. Overview Tips and tricks in the following areas: Execution Control Breakpoints Symbols Multi-threaded Debugging Postmortem Debugging Data Viewing Behind the Debugger Magic

4. VS Debugger Overview Debugs many different code environments Native Windows X86 X64 IA64 Managed code Windows (32bit and 64bit) SQLCLR Script T-SQL Native device programs And many, many more…

6. Overview Tips and tricks in the following areas:  Execution control Breakpoints Symbols Multi-threaded Debugging Postmortem Debugging Data Viewing

7. Execution Control NEW SP1 Step Filtering for Managed Adds support for automatically stepping over simple properties Right click to “step into specific” pick step into target

8. Step Filtering

9. How it Works: Step Filtering Step in as normal If (stepcomplete outside of targetrange) { complete as a step over } Else If (step completed as a stepin) { If (current location is property || current location is operator) { Step out and try another stepin }

10. How it Works: Step into Specific Disassemble instruction range for line Populate drop down with targets User selects specific call If (stepcomplete outside of targetrange) { complete as a step over } Else If (step completed as a stepin) { If (currentframe return != target call location) { Step out and try step in again }

12. Tracepoints Print a variety of program state types without stopping Program location, including stack Expressions (including @clk in native for quick timing) Thread info Run a macro Useful to stop on a certain condition that is difficult to express as a “watch window” expression (for example, “Stop if this method is in the callstack”)

14. Overview Tips and tricks in the following areas: Execution Control Breakpoints  Symbols Multi-threaded Debugging Postmortem Debugging Data Viewing

15. Symbols You’ve got to hold them squeeze them never *EVER* ship without archiving them Ensure symbols are switched on in final/retail/optimized builds Archive symbols using symbol server

16. Setting Up and Using a Symbol Server Download windows debugging tools Get a file server with a big hard disk Build daily build Use SYMSTORE to push binaries and PDBs to fileshare e.g.: SYMSTORE add /r /f c:\BUILTFILES\*.* /s \\MYSERVER\SYMBOLSHARE /t “Application” /v “BuildVersion3” \\MYSERVER\SYMBOLSHARE Point Visual Studio to that share and set a local cache

17. Symbol Paths

18. Symbols NEW SP1 Reference Source Support

19. Symbols

20. VS Never loads mismatched symbols Never. Never, ever. Path plan is where the exe thinks it is on the path we create from the symbols dialog on the path at HKLM/HKCU Software\Microsoft\VisualStudio\MSPDB\SymbolSearchPath on the path at any of these _NT_ALT_SYMBOL_PATH _NT_SYMBOL_PATH SystemRoot Use Right Click on Module -> “Symbol Load Information…” to find out where we looked Symbol Loading Internals

22. NEW Thread Categories and Flagging Threads

24. Using Breakpoint Filters Right-click on breakpoint, select Filter… Freezing and Thawing Right-click on thread, select Stack Tips and Thread Flags Naming Threads Managed – Thread.Name Native – Use the SetThreadName exception wrapper See resources at end of deck…

25. Tips and tricks in the following areas: Execution Control Breakpoints Symbols Multi-threaded Debugging  Postmortem Debugging Data viewing Overview

26. Post Mortem Debugging Increasingly important as Microsoft continues to invest in Windows Error Reporting ISVs can participate in WER by visiting http://winqual.microsoft.com http://winqual.microsoft.com Create an account Complete a request file mapping form Enterprise customers can use CER to keep data local and verify/analyze See resources at the end

27. Postmortem debugging

28. Postmortem – Optimized tips Take the red pill! Open the disassembly window Open the autos window to see pertinent registers Trust statics/globals and trust stacks when you have symbols You do have symbols right? Don’t necessarily trust Watch and Locals Not enough information is around for the debugger to make sense of which variable is alive
