After Rhino 6 Installation C# Interfaces complaining about previous rhinocommon version


How to correct the following so that I would not have any warning messages?
What is causing that?

  1. Warning (CS1701): Assuming assembly reference ‘RhinoCommon, Version=5.1.30000.13, Culture=neutral, PublicKeyToken=552281e97c755530’ matches ‘RhinoCommon, Version=6.0.18016.23451, Culture=neutral, PublicKeyToken=552281e97c755530’, you may need to supply runtime policy

  2. Warning (CS1701): Assuming assembly reference ‘Grasshopper, Version=, Culture=neutral, PublicKeyToken=dda4f5ec2cd80803’ matches ‘Grasshopper, Version=6.0.18016.23451, Culture=neutral, PublicKeyToken=dda4f5ec2cd80803’, you may need to supply runtime policy

Found it, it was all Kagaroo2 .dll files, now they are placed into general grasshopper components folder.

Hi Petras,

I’m also facing this problem. Which folder is the “general grasshopper commpoents folder”? The one under Rhino install folder or under c:/user one? Thank you for your help.



Kangaroo 2 is included for RH6, so i had to remove all Kangaroo files from APPDATA/Roaming/Grashopper/Libraries, ale link to KangarooSolever.dll in C:\Program Files\Rhino 6\Plug-ins\Grasshopper\Components to remove this error.
