For example, on the 'Socket' class the EndSend method, appears to cancel a pending async send, but on most other Begin/Send methods (Webservice methods for example), it seems to provde a 'helper' method to get hold of the async result, but again it isn't clear to me what the correct approach is in this case :) (the article appears to suggest the latter)! - Ciaran > > *From:* Ciaran [mailto:[EMAIL PROTECTED] > *Sent:* 16 January 2008 12:07 > *To:* Kieran Benton > *Cc:* [email protected] > > *Subject:* Re: Enyim.Memcached and asynchronous sets > > > > > > On Jan 16, 2008 11:50 AM, Kieran Benton <[EMAIL PROTECTED]> > wrote: > > Hi Ciaran, > > I think this is definitely something that would be of benefit, as you're > right, if you've architected your app correctly most SETs can be > asynchronous.
