I just started to work with the new build of AppsBuilder (188.8.131.52) and with some of the newly available samples.
I recommend that, as you start do work with the updated version, you should do a build of your projects, when recompiling them for the first time. If you don’t do a full build, you might get some compile time errors. Doing a full build, once, does away with this problem and you are home free.
In the next couple of days I will be doing posts commenting on the some of the new samples, individually. My focus will be letting people know what they can expect to learn, if they dive into each of these applications.
