How often do you see this pattern (or variations on it)

try{
…some code…
}
catch{
throw;
}

Sometimes it will be catch(Exception ex) or catch(SomeParticularException ex), and sometimes it will be throw; or throw ex;, there is no finalizer block, but the important thing is that NO OTHER ACTION IS TAKEN (no logging, no retry, nothing else in the catch block).

As far as I can tell, this is equivallent of wrapping code in NOP (no-operation) commands.

Please don’t do this.
