asynchronous

in this sample, two threads created; a worker thread created by BeginInvoke and an I/O completion thread created by SendAsync method.

but another author in his UnsafeQueueNativeOverlapped example, don't recommend this.

i want to use SendAsync or ...Async in an asp.net page and i want to use PageAsyncTask. however, its BeginEventHandler requires AsyncResult to be returned which SendAsync does not return.

afaik, event based async pattern is the most recommended way so how could we call SendAsync or any ...Async methods without creating two threads and hurting the performance?
