how to start with the .NET API for DropBox for Business

Hello,

maybe my question is a bit complicated. So I will explain what I have to do.

I have to build an application to manage technical drawings for our company.

There will be a shared database (using a webservice we already have), and in that database we will store where the drawing effectively stays.

The drawings files itself should be shared through DropBox, and it depends on the type of drawing what users should have what type of access to it: modify, read or no access at all.

There are two types of users: internal users (that should access the drawings on the drive on the local server - we manage the rights internally, and the server should do the synchronization with the DropBox folder) and external users that will have the files on their local disc, maybe using SmartSync.

The rights and where the files should stay should be managed directly in the application.

The first thing I need to know what objects/classes I need to store a file in the DropBox folder and to assign the rights to them (we will build groups ourselves, and if the group changes, the application should take care of the changed rights).

Thank you very much for any hint!
