If I have a method or a property that returns an IEnumerable<SomeType> that leads to no data,
is it more efficient to return an empty array new SomeType[0] or is it better to return an empty list new List<SomeType>() or is there an even better solution (IMO building an own type with generics could be such a solution but it seems to me a little bit overkill)?
The array is my favorite but what do you think about this?
Return
Enumerable.Empty<T>().
