I like to compile a simple GH definition into a plugin.  
I get an Error (CS1009).  
What is wrong here?

Thank you!

I don’t know the tool used here, but to make it easier for others to understand the error code: [Compiler Error CS1009 - C# | Microsoft Learn](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-messages/cs1009)

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?
