C3D 2022, No Function Definition with LispFunction

[CodeDing]

Hey All,

I'm hoping this can be an easy fix for some of you experts. I'm by no means totally proficient with C#/.NET/Visual Studio yet. Trying to get better. Anyways...

In short.. Trying to create a Lisp Function via .NET (C#). I've created some Lisp Functions via this API in the past, but now that I've switched over to Civil 3D I can't seem to get something right?

I have a SIMPLE method / function:

using System;
using System.Windows;

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.Runtime;

namespace Test
{
    public class Testing
    {

        [LispFunction("test")]
        public static void RunTest(ResultBuffer rbArgs)
        {
            Autodesk.AutoCAD.ApplicationServices.Application.ShowAlertDialog("Hello World!");
        }
    }
}

There are no build errors:

I believe I have all the correct dependencies referenced:

Yet, when I run the function, it does not exist:

Please can I get some advice to get over this hurdle?

Best,

Hi,

Is Copy Local property equal to False for each AutoCAD reference ?

[CodeDing]

Correct, they are all set to "No".

@CodeDing ,

I think you started a wrong project type with your Visual Studio (2022, it looks to me). I tell this from 2 pictures you attached in your post. 

1. The picture in your first post showing the references, it shows as "Dependencies", rather than "References" a it is supposed to be;

2. The picture attached to your reply to @_gile shows "Copy Local" to "No", rather "False" as it is supposed to be.

These 2 things indicate that you have chosen the project as .NET Core (.NET5/6), rather than .NET framework (4.7x/8). AutoCAD .NET API CAN ONLY work with .NET Framework, not .NET Core/5/6. You need to recreate your class library project as .NET Framework class library.

@norman.yuan ,

You are exactly correct. I did not know that. Thank you very much!
