It's C# so it's just rethrowing the original exception.
It might also be messing with the stack trace though which can be a bit frustrating for future debugging. But that's only a vague recollection of something I read in the past so I could be wrong
Throwing exceptions are very costly due to the stack trace, so building the stack trace twice will cause a big performance hit
Correct me if I'm wrong, but this will actually cut the stack trace and then start another one from your try-catch block, which is an evil thing to do towards those who will actually read your stack traces. To preserve the stack trace you do
throw;, notthrow ex;, and I'm assuming IDE is underlining that statement exactly for this reason.Yes, hence why I mentioned it collects the stack trace twice.
It's more than just more difficult for debugging
