Title: Advanced .NET Debugging


1
Advanced .NET Debugging
  • Auto-expansions
  • Attribute Usage for debugging
  • MSIL and the CLR
  • Tools
  • ILDASM
  • ILASM
  • CORDBG
  • Dotfuscator
  • SoftIce !!!

2
Auto-expansions
  • Expansion files allow you to display more
    information in the Watch window
  • MSEE_CS.dat, MSEE_MC.dat and autoexp.dat
  • ltVS .NETgt\Common7\Packages\Debugger
  • All file documentation is in BNF (Bakus-Naur
    Form)
  • Eg. ltSystem.Threading.ThreadgtNameltNamegt

3
Auto-expansions
  • Before editing MSEE_CS.dat
  • After editing MSEE_CS.dat

4
Auto-expansions
  • Microsoft forgot(?) to add Auto-expands for types
    like StringBuilder
  • You can add Auto-expands for your custom types
  • Auto-Expands are also visible on the tool tip

5
Attribute Usage for debugging
  • DebuggerStepThrough attribute
  • Can be applied to classes, methods, structures
  • VS .NET debugger steps over attributed item even
    if you use Step Into (F11) Command.
  • You can still set up break points in the
    attributed item if you want to debug them
  • Supported by DBGCLR.EXE, but not by CORDBG.EXE

6
Attribute Usage for debugging
  • DebuggerHidden attribute
  • Can be applied to classes, methods, structures
  • VS .NET debugger steps over attributed item even
    if you use Step Into (F11) Command.
  • You CANNOT set up break points in the attributed
    item at all.
  • Supported by DBGCLR.EXE, but not by CORDBG.EXE
  • Handy tool for hiding internal methods (not
    foolproof)
