Update: tried with Jetbrains Rider and same errors. Will try on Windows and see if these errors persist

Rhino.Common seems to support only .NET Framework 4.8 So: * net7.0 is way too new to support this package * You won't be able to use it outside of Windows

Thanks for the reply! I am aware of that, but based on Rhino devs it should work despite what seems to appear in Nuget: - https://discourse.mcneel.com/t/rhino-inside-net-core-7-0/166059/5?u=gabriel15 - https://developer.rhino3d.com/guides/rhinocommon/moving-to-dotnet-7

You won't be able to use it outside of Windows

That would be true if the package is compiled for .NET Framework 4.8, right?

Yes, .NET Framework is Windows-only That said, even .NET Core and .NET applications and packages can be limited to Windows-only Especially if they use Windows-specific functionality

Got it, thanks! I did the installs on the Windows machine, same setup, and still getting that error; so I'm definitely doing something wrong 😆
