Difference between License for Scheduler and Scheduler.NET

I will be interested to get the license for the DHTMLX Scheduler. Just have a quick question on the licensing, when I go to get the license on DHTMLX site, it states two different versions, DHTMLX scheduler and DHTMLX Scheduler.NET. Could you please explain the difference between the two licenses, though both have the same licensing fees.

There are two products

Scheduler.Net is a .Net wrapper around the normal Scheduler, it allows to configure most settings of Scheduler through .Net code. Also it contains extra docs and samples for using Scheduler with .Net backend.
