Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IAsyncCursorSourceTDocument. 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).
Remarks
If your delegate is going to take a long time to execute or is going to block
consider using a different overload of ForEachAsync that uses a delegate that
returns a Task instead.
