Hey @xliotx,
Yes, Rhino 8 can run in either .NET Framework or .NET Core runtimes, you can tell it which runtime to use by passing either /netfx or /netcore as arguments. You can see a sample launchSettings.json file here how you might be able to debug Rhino 8 in either runtime, and Rhino 7 using the same project. launchSettings is configured using VS’s launch profiles dialog.
