Hey,
It does work when defining ex but I appreciate you taking the time to show a better way so thank you.

To define ex, you would do it the following way:
try
result = 10/0
catch ex As Exception
throw ex
end try
This is what you see everywhere, so it is repeated everywhere else. But what I showed you is better because you keep the StackTrace.

Yup, VS does that part for you, I typed it in the editor so I forgot that :)

An even if it was, rethrowing a catched exception removes the stacktrace, one of the best piece of information you can have in an exception.
The right way to do it is even simpler, and it keeps all the information intact:
catch
throw
