Rhino.Inside Unity - Sample problems

Hello everyone,

I’m trying to open the samples from https://github.com/mcneel/rhino.inside/tree/master/Unity
Following the instructions, doesn’t work for me.

Sample1:
I tried opening it with 2018.3.0f2 and newer versions.

Assets\Standard Assets\RhinoInside\Unity.cs(44,53): error CS0103: The name 'Rhino' does not exist in the current context

Assets\Standard Assets\RhinoInside\Convert.cs(5,7): error CS0246: The type or namespace name 'Rhino' could not be found (are you missing a using directive or an assembly reference?)
etc.

Sample2:
When starting Grasshopper inside Unity, it simply freezes.

Anybody got similar experiences?

Thanks in advance,
Tim

Side question (maybe I should open another thread in another forum):

I’m able to use Rhino.Compute in Unity with my local server. If I add the RhinoCommon.dll (RH6) ofc I get two namespaces called Rhino (one from Rhino3dmIO.dll (RH7) which is used for Rhino.Compute and one from RH6). Using extern alias for RhinoCommon.dll needs to be defined in Unity outside of the script in a “platform dependent compilation” csc.rsp. (-reference:RH6=Assets/Plugins/RhinoCommon.dll)
But still, doesn’t work. Anybody faced a similar situation?
