Maybe it is a silly question. The Task class is declared this way: public class Task : IThreadPoolWorkItem, IAsyncResult, IDisposable The IAsyncResult interface is declared like this: public i...

I've just come across IAsyncResult recently and have played with it for quite some time. What I'm actually wondering is why use IAsyncResult when we have a way better alternative ThreadPool there? ...
