Usage Note

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