One thing you could do in the Main calling method:
static numRequestsImMaking = 10;
.....
// instead of exiting the method immediately (or Console.ReadLine)
// wait for all results to complete
while (numRequestsImMaking > 0){
System.Threading.Thread.Sleep(500);
}
Then, in your AfterInfoFetch method, call:
Interlocked.Decrement(numRequestsImMaking);
That should work. A better way than polling might be to use a
WaitHandle. Check the .NET Framework docs for the available derived
classes of WaitHandle.

I think you will have to show more details of CallAsyncMethod().
How are you making the asynchronous calls? If you are creating your own
threads, you can use Thread.Join().
You can also set the threads so that their IsBackground property is
false - this will prevent the app from ending before those threads complete.

my problem is when i run the app console exists without really completing
DoSomething()
if i add 'Console.ReadLine() to Main() then console waits until
DoSomething() is complete
how do i make the app exist only after DoSomething() is complete?
