Anyone else out there get annoyed with the "Attach Security Warning" dialog?  It gets pretty annoying when you attach to multiple processes (ie: w3wp.exe) and have to click 'attach' for each process every time you debug... anyhow, solution is below...

Find the following registry keys:

  • Visual Studio 2008 - HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\Debugger\DisableAttachSecurityWarning
  • Visual Studio 2005 - HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\Debugger\DisableAttachSecurityWarning

Change the value from 0 to 1.

Done!
