Hi. Could someone explain why this is the case?

longHeroes is of type IEnumerable<T> , not List<T> , so we use the method Count() , not the property Count .

I understand that IEnumerable in not a List and therefore doesn’t have Count property.
What I don’t understand is where exactly does Count() method come from? I checked Microsoft documentation and the only method listed under IEnumerable is GetEnumerator.

Is it inherited from somewhere else?

Edit

Found it. If any one is interested, it’s listed as one of the methods under Enumerable in System.Linq namesapce.

Count()
