Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type 
IEnumerableT. 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).
