This tutorial is like a KinderSurprise. It has three things, an introduction to Flash Builder, an introduction to Flex and finally a great introduction to connecting to an AMF service.
Also looks like there will finally be something to replace the oh-so-missed class generator that existed back in the previous AMFPHP versions.
Seeing Flash Builderm I am still not clear as to what the difference is between the Flex builder and Flash builder. Especially seeing a Flex app being built in Flash Builder. but I am sold on the whole Catalyst/Builder concept since first seeing it over at the labs. Yeas I admit it, I have been dabbling around without in my freetime. No matter what some people say, Flash is not about to die just yet.
