Encounter Error (CS1009) while trying to compile a GH definition into RHP

[wim (Wim Dekeyser)]

@Quan_Li

I am trying to turn a GH definition into a plugin with Rhino Script Compiler.

That’s working fine with your .gh file here.
That said, the Rhino 7 script compiler is now legacy technology. Have you tried using the ScriptEditor in Rhino 8?
