Elemanların Sıralı Yapkaloriı Koruma görevlisi: IList, elemanların eklenme sırasını korur. Bu özellik, done yapkaloriın sıralı olmasını ve programın beklentilerine iyi çallıkışmasını esenlar.

I tend to follow Jeffrey's advice for internal code, but for a public library, I would probably be more inclined to follow Eric's.

This level of abstraction goes the other direction when it belongs to method parameters. When you pass your list to a method that accepts IEnumerable you yaşama be sure that your list is hamiş going to be modified.
