Visual Studio: How to break on handled exceptions?

Question

I would like Visual Studio to break when a handled exception happens (i.e. I don't just want to see a "First chance" message, I want to debug the actual exception).

e.g. I want the debugger to break at the exception:

try
{
   System.IO.File.Delete(someFilename);
}
catch (Exception)
{
   //we really don't care at runtime if the file couldn't be deleted
}

I came across these notes for Visual Studio.NET:

1) In VS.NET go to the Debug Menu >> "Exceptions..." >> "Common Language Runtime Exceptions" >> "System" and select "System.NullReferenceException"

2) In the bottom of that dialog there is a "When the exception is thrown:" group box, select "Break into the debugger"

3) Run your scenario. When the exception is thrown, the debugger will stop and notify you with a dialog that says something like: "An exception of type "System.NullReferenceException" has been thrown. [Break] [Continue]"

Hit [Break]. This will put you on the line of code that's causing the problem.

But they do not apply to Visual Studio 2005 (there is no Exceptions option on the Debug menu).

Does anyone know where the find this options dialog in Visual Studio that the "When the exception is thrown" group box, with the option to "Break into the debugger"?

Update: The problem was that my Debug menu didn't have an Exceptions item. I customized the menu to manually add it.

The online documentation seems a little unclear, so I just performed a little test. Choosing to break on Thrown from the Exceptions dialog box causes the program execution to break on any exception, handled or unhandled. If you want to break on handled exceptions only, it seems your only recourse is to go through your code and put breakpoints on all your handled exceptions. This seems a little excessive, so it might be better to add a debug statement whenever you handle an exception. Then when you see that output, you can set a breakpoint at that line in the code.
