Does Enumerable.AsEnumerable<>() force the evaluation of the expression?

Question

string[] fruits = { "apple", "passionfruit", "banana", "mango",
                  "orange", "blueberry", "grape", "strawberry" };
List<int> lengths = fruits.Select(fruit => fruit.Length).ToList();

Enumerable.ToList() or Enumerable.ToArray() performs eager evaluation, they force the evaluation. Does Enumerable.AsEnumerable() do the same ?

Thanks

In short, no. It does absolute nothing at all, it just return the input collection, typed with a different interface.

It's only practical purpose it to switch from IQueryable<T> to IEnumerable<T>, so that further LINQ methods are performed with the enumerable version instead of the queryable, making evaluation to go to "client-side".

But, in itself, it doesn't do anything.
