expected-exception

I'm using SpecFlow, and I'd like to write a scenario such as the following:

Scenario: Pressing add with an empty stack throws an exception
    Given I have entered nothing into the calculator
    When I press add
    Then it should throw an exception

It's calculator.Add() that's going to throw an exception, so how do I handle this in the method marked [Then]?

However, when I change the unitTestProvider… >>> More
