Not sure about VS 2008, but at least in 2010 and later you can go to Debug / Exceptions (Ctrl-Alt-E). Click the Add button, select General Language Runtime Exceptions, and enter:
Microsoft.VisualStudio.TestTools.UnitTesting.AssertFailedException
and click OK. Now it will appear in the list, make sure you check the box in the "Abandoned" column. Now you will receive a break in any denial.
