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;, not throw ex;, and I’m assuming IDE is underlining that statement exactly for this reason.
Throwing exceptions are very costly due to the stack trace, so building the stack trace twice will cause a big performance hit
