Editor's Notes
- What if an error is appearing in production, and you don’t have proper logging?
- https://msdn.microsoft.com/en-US/windows/desktop/bg162891 Comes with so many tools, but you can uncheck the boxes
- Be careful; displaying the call stack in Windbg puts the variables below the method that uses them!
- Sync Block can be used to synchronize access to this object between the threads Type Handle contains information about the Type, e.g. methods.
- These are extensions you need to have a beautiful experience debugging with WinDbg SOS comes with the .net framework SOSEX you can download from Steve’s Techspot blog
- You need to specify a symbol source: cache, local folder, or/and symbol server.
