DocumentDB project for Visual studio like existed SQLServer project.
It's would be valuable if we will can save all collections and related scripts in a new type visual studio project. Now only in a database we can observe UDFs, triggers and so on.
Another option for a project could be compare .js objects in a collection. With a project we would have a chance to compare already deployed versions of our scripts with current developer version of the script.
This is not on our roadmap. Will mark as unplanned and leave open in case this changes.
Thank you for your suggestion.
