Right, I see what you mean. I was just working on a class that had a property that has to be a number between 0 and 255. The assert checks it being entered incorrectly at design time and the assign handles it at runtime.
Thanks.
>Yes, you can use asserts exactly like that. In my case it's not really as much a "design time" error as it is a safety valve.
