.NET compiled and runs on 2014... will it run 2015... 2016?

Given a .NET application... will it need to be recompiled to run in 2015 AutoCAD?

The NDA is still active.  Those that know, cannot say.

if the main dll changed,mayby you need recompile to 2015

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".
