http://blogs.msdn.com/b/carlosfigueira/archive/2009/07/23/chaining-async-calls-in-wcf-or-in-net-in-general.aspxRecently I had to implement an asynchronous operation which would in turn call another asynchronous operation (i.e., cascading async operations). For simple cases, when there's no intermediate processing in the middle of the chains (i.e., no new stateen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/carlosfigueira/archive/2009/07/23/chaining-async-calls-in-wcf-or-in-net-in-general.aspx#10276018Thu, 01 Mar 2012 22:45:50 GMT91d46819-8472-40ad-a661-2c78acb4018c:10276018CarlosFigueira<p>Great, thanks.
