Jason Diamond didn't like the Ajax.Net
framework so he wrote his own one called My
Ajax.Net. The latest release of the library is available from here (currently
it is version 5). The advantage of this library over the Ajax.Net implementation
is setup and configuration. He has avoided a custom IHttpHandler to process
callbacks which has its pros and cons. The argument he poses for doing this
is that you may want to access the controls on the page that the control is sitting
on. That's fair enough, but you may also want to avoid that overhead altogether
and not reload all the data for the controls and just deal with your control in isolation.
