PowerBuilder 12.5 introduced a number of significant enhancements to web services support, both for creation and consumption. In particular, the following were introduced as new features in PowerBuilder.NET: WCF client proxy WCF service target REST client proxy We're going to look at what those new features provide and how to use them.

In case that sounds like Adobe abandoned Flash entirely, it should be noted that Adobe indicated their intentions to continue to develop the AIR player for mobile devices, so that the role for Flash on mobile devices would be restricted to native apps, just not browser-based apps.
