What is this library for?
Library is used for plugin development. For details Check here
Rhino_DotNET.dll located in the Rhino system directory. The Rhino_DotNET.dll assembly is what all Rhino.NET plug-ins reference to get exported classes and functions from Rhino. This file is installed with Rhino and is not a separate download.
I know it is part of the installation. I was looking more of what is its difference compared with RhinoCommon.dll?
RhinoCommon.dll - This is a pure .NET DLL that plugins can reference and use to work with Rhino.
Both the answer’s available I hope now you can find the differences. @ivelin.peychev
I do not understand the following:
I thought RhinoCommon has these classes.
Rhino_DotNet is an old and depracated library that was written a long time ago. It’s functionality has been replaced by RhinoCommon.
Don’t use it.
