Instructions

  1. Follow the instructions here to enable WER. Make sure the DumpType is set to 2 (Full Dumps).
  2. Make a new Module (static Class in C#) called ProgramEntryPoint.
  3. Copy the code written below and don't forget to change YOUR_STARTUP_FORM_NAME_HERE.
  4. Change project configuration to Debug
  5. Go to Project Properties. In the Application tab, uncheck "Enable application framework".
  6. Change Startup Object to Sub Main.
  7. Go to Debug -> Windows -> Exception Settings and make sure Common Language Runtime Exceptions is checked (full checked and not partially checked).
  8. Now whenever an unhandled exception occurs, your application will quit and a .dmp file will be created in the folder specified in the DumpFolder registry key.
  9. Open the .dmp file in Visual Studio
  10. Click on "Set symbol paths". Make sure Microsoft Symbol Servers is enabled and add the path to your PDB files as well.
  11. Click on Debug with Mixed. If you've followed all the instructions, it should take you right to the line in the source code where the exception occurs with all variables and stack trace intact.
