Quoted from MSDN:

To break execution when an exception is thrown

On the Debug menu, click Exceptions.

In the Exceptions dialog box, select Thrown for an entire category of exceptions, for example, Common Language Runtime Exceptions.

-or-

Expand the node for a category of exceptions, for example, Common Language Runtime Exceptions, and select Thrown for a specific exception within that category.
