In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
This a pass-through operator that uses deferred execution and
streams the results.
