Grasshopper Developer

Kangaroo 2 custom plug debugging is not working. I am using Rhino 6, Visual Studio 2015, dotnet framework 4.5.
Reference added, Kangaroo Solver 2.4.2, GH_IO, Grasshopper, PlanktonGH and Plankton.
I have an urgent deadline. Please let me know, why I am not able to debug. The data is not accessible.
I have similar question in the past. But later I could solve the problem. The problem came back again after started to use Rhino 6 evaluation version.

OK. Found from where to add reference for KangarooSolver.dll

C:\Program Files\Rhino 6\Plug-ins\Grasshopper\Components
It worked after adding reference from this location.
