Error when following Rhino Inside Instructions

I followed the instructions for Sample 2 of Rhino.Inside and was getting this error when I tried to run the program.

I noticed that the dependencies for the Rhino.Inside nuget still has the wip versions of RhinoCommon, RhinoWindows, and Grashopper. Was wondering if maybe that had something to do with my error since the only nuget packages for those I can get are the ones for the full 7 release and not the wip versions.
