The NDA is still active. Those that know, cannot say.
I am testing this right now. Everything I have for 2014 was written with .NET framework 4.0. Nothing is compiling after swapping the references from 2014 to 2015 (accoremgd.dll, acdbmgd.dll, acmgd.dll).
I wonder if 2015 requires .NET framework 4.5?
I am able to load a .dll that was compiled for 2014 (.NET framework 4.0) into AutoCAD 2015 using NETLOAD. Unfortunaltly I cannot get the .dlls to load using Autoloader and a .bundle folder as I do in 2014.
So, I tried to create a small sample project in Visual Studio by using AutoCAD 2015 references, but it won't compile. I thought maybe I didn't have .NET Framework 4.5 installed as it didn't show up in the target framework list in VS. After thinking about it, I realized that AutoCAD 2015 probably wouldn't even run without the 4.5 framework, so it must already be installed (which it was).
After diging into it, I discovered VS2010 does not support the 4.5 framework! Grrrrr! I guess it's time to "upgrade".
