Does AsEnumerable() cache all result (LINQ)

Question

When we call a query operator on a sequence, a sequence-specific operator gets called.
I mean if i call Where<>() operator on IEnumerable<>

Answer 1

IQueryable extends IEnumerable, so the AsEnumerable is redundant. However, if you use it, AsEnumerable is not going to greedily load the collection (that would be a very annoying "feature"). Clearly, Reverse will need the whole thing. Mono implements Enumerable.Reverse using a List and a simple iterator-generator that yields in reverse.

I believe the only real purpose of AsEnumerable is to force the use of IEnumerable explicit interface implementations.
