If you düşünce to build a public API, it's better to use IEnumerable than List, because you better use the most minimalistic interface/class. List lets you access objects by index if that's required.
. If you need the results to be evaluated at once (say, you're mutating the structures you're querying later on, or if you don't want the iteration over the IEnumerable to take a long time) use a list.
