Flash Builder Max Preview migration guide to Flash Builder 4.5

Most of this actually is related to Mobile development with AIR, considering there isn’t a bunch of desktop development focus in the SDK.

And what about if we’re doing a browser application that we want to save a state of something, but don’t want to host the storage and write a web service to handle data?
We don’t have stealth access to the filesystem directly, which makes it hard (errr, impossible) to silently store things on behalf of the user.

We can actually tackle both easily using serialization.

Grant Skinner braves the daunting task of telling all of us what we should know (and I assume that we DON’T know). Either way, it had a kickass intro… Wonder what the track was.

A set of his slides can be found on his website:
