Do you have to call EndInvoke (or define a callback ) for asynchronous method calls even if you don't have anything to do when it returns

Question

I found the following code snippet on CodeProject on calling methods asynchronously at ... http://www.codeproject.com/Articles/14931/Asynchronous-Method-Invocation

Answer 1

As a matter of practice, you should call EndInvoke because the caller may have handlers subscribed to the events that may not matter to your processing, but may matter to the consumer so as to ensure certain kinds of processing can take place at a known time/application state.
