Async in C# 5.0: Async methods and return value

Async in C# 5.0

Async methods that return task allow the caller to wait for the operation to finish, and propagate any exception that happended during the asynchronous operation. When no result value is needed, an async Task method is better than as async void method because it allows the caller to also use await for it, making ordering and exception handling easier.
