.NET Core vs .NET Framework

by Brian Gillespie (Last updated: Friday, January 19, 2024)

Rhino 8 uses .NET Core by default.
On Windows, some older plug-ins will not run when .NET Core is active, requires the legacy .NET Framework, instead.

TO change Rhino to always use .NET Framework:

1. Start Rhino for windows
2. Type the command SetDotNetRuntime
3. Select the Runtime option
4. Set the .NET Framework option
5. Close Rhino

TO start Rhino in .NET Framework once:

Caution: only recommended if you have a plug-in that doesn’t run in .NET Core.

1. Create a new shortcut for Rhino in Windows
2. Edit the shortcut
3. Add command line argument /netfx

To start Rhino in .NET CORE once:
