Microsoft recommends that you call asynchronous methods in your code whenever possible for optimal performance. The recommended methods are those that use the Async/Await pattern. For more information about asynchronous programming in .NET with Async/Await, see Asynchronous Programming with Async and Await (C# and Visual Basic).

The corresponding method that uses Async/Await is ChangeLeaseAsync.
