The site lists three reasons to use Revit AppStore:
- Run your apps from anywhere
- Easy way to find new apps
- It's Free!
The site asks:
So, are you a Developer?
The RevitApp Store SDK is small and simple to use. It is based on an IExternalExtension interface that is the communication with the RevitApp Store. The Apps you create will be protected against copy and execution outside of the Revit AppStore using an AppProtection class.
It also invites us to suggest applications that ought to be available. It will be interesting to see how it develops (pun intended).
