Asynchronous Programming in Web Services

Callback functions are the way to implement Asynchronous programming in Web
services... We will get into details of this topic sometime but now just an
overview...
A client calls the Begin method on the server object and passes a reference
to the callback method... The asynchronous method on the server object
finishes execution and gives a call back to the method on the client
object... This method in client object now causes the call to End method on
the server object.... The End Method then returns the result to the
client...
Well why would you do such a thing??... The simple reason can be when your
server side execution is really going to take long and you do not want to
wait for all that processing to happen...
