@dale When bringing in RhinoInside nuget package v7.0.0 RhinoWindows.dll does not get copied into the Bin folder. RhinoInside expects the Version=8.0.0.0, Culture=neutral, PublicKeyToken=552281e97c755530. The nuget package RhinoWindows 8.0.21131.12305-wip does not seem to produce the RhinoWindows.dll in the Bin folder either. The version in the Rhino folder is 7.4. What am I doing wrong? Thanks
