The one new feature you absolutely must understand to build applications on Fuji

[nsimha]

And that would be Application Scope.   The goal behind application scope is to ensure that an application running in an instance of ServiceNow plays nicely with every other application running on that instance i.e. doesn't impact other applications adversely.   This applies to all applications whether built by ServiceNow, developed in-house by the enterprise or purchased from a partner.   If you are familiar with namespaces in other languages like Java, it is somewhat similar to that however unlike namespaces application scope has broader implications and affects code visibility, access control, versioning and more. Since this is a fairly fundamental change in the platform in Fuji, we have multiple sessions at CreatorCon on this topic.

@Joe Davis from our product development groups and a key platform architect will be leading a breakout titled Under the hood - Application Model on Thursday afternoon.   This session will go over all the implications of application scope through short demos.   Also on Thursday afternoon, you can also attend a hands on workshop - Converting pre-Fuji applications to scoped applications that is being conducted by     Bobby Edmonds and David Gatley   Bobby and David are back Friday morning to deliver another workshop   Managing application lifecycle with application model in Fuji .   We are ofcourse chaperoning Bobby and David Thursday evening at the House of Blues party so that they do make it to the conference Friday morning.   All applications that are to be listed on the Store has to be scoped applications so this topic will get coverage in Building Orchestration Applications and getting them ready for ServiceNow Store workshop being delivered by Jonathan Koster and Carleen Greenlee.  

This is also one of the focus areas in our developer lounge so if you cant attend one of these sessions, you can still get your questions answered.  

I encourage you to check out the wiki documentation and this blog by David Gatley to get yourself familiar with application scope.   Also, please post any questions that you may have on this topic below for our presenters.
