Earlier today, it came up in discussion, on when to catch exceptions. Really, you end up getting bitten if you just catch exceptions in your code. Basically what happens is that you are using exceptions as flow control, and not using if/end, etc. What usually ends up happening is an exception is getting eaten, but you didnt want it to, and you dont know how your program is reacting to use. ELMAH is great, you should set it up if you are using .NET programming. Also, and it is funny, but this always happens, Scott Hanselman blogged about almost the exact same topic today. And if you can avoid, dont catch a System.Exception – use a more specific exception. If you turn on Code Analysis or run FxCop, it will tell you about that as well.
