What interface should my service return? IQueryable, IList, IEnumerable?

Question

Imagine I have a SearchService layer that has a method to search all cars starting with a certain string;

public static class Searcher{
    public IAnInterface&l         


        

Answer 1

I would choose IEnumerable because it has a more central place in the framework, providing versatility for those that need it, while also providing familiarity to those who are yet to get stuck into things like LINQ.
