  • breakpoint:

    1. start dnSpy as admin

    2. menu "Debug" -> "Attach to process"

    3. select w3wp.exe

    4. menu "Debug" -> "Windows" -> "Modules" to see all loaded assemblies

  • if local variables didn't show (JIT optimization):

    • by updating assembly attributes: hacktricks/reversing.md at master · carlospolop/hacktricks - Reversing - HackTricks

      [assembly: Debuggable(DebuggableAttribute.DebuggingModes.Default |
      DebuggableAttribute.DebuggingModes.DisableOptimizations |
      DebuggableAttribute.DebuggingModes.IgnoreSymbolStoreSequencePoints |
      DebuggableAttribute.DebuggingModes.EnableEditAndContinue)]

    • For ASP.Net, set configuration/system.web/compilation/@debug to true (Web.config) to disable execution optimizations (see also @optimizeCompilations, set to false) (only for generated code?)

    • by use ini file or registry:

      • set the environment variable COMPLUS_ZAPDISABLE=1 or the registry key HKLM\SOFTWARE\Microsoft\.NETFramework\ZapDisable

      For ASP.Net, set system.web/hostingEnvironment/@shadowCopyBinAssemblies to false (Web.config) to disable shadow copies of DLLs (in a tmp dir)

      For the DLL somelib.dll create a somelib.ini with:

      [.NET Framework Debugging Control]
      GenerateTrackingInfo=1
      AllowOptimize=0
