.NET API - cannot load the DLL files

[Anonymous]

Hi, 

I am trying to use the API but every time I run my application, it comes up with the following errors depending on which "Platform target" option I choose.

This is my simple program:

using System;

using Autodesk.Navisworks.Api;

namespace ConsoleApp4
{
    class Program
    {
        static void Main(string[] args)
        {
            Document doc = Autodesk.Navisworks.Api.Application.ActiveDocument;
            Console.WriteLine(doc.Title);
        }
    }
}

The DLL files are located in "C:\Program Files\Autodesk\Navisworks Manage 2019" where I load them from. See below:

I tried to copy the files to a different folder - this does not help. I also have a full professional licence. Any ideas how to make this work?

Hi @Anonymous ,

if you wanted to build a standalone EXE program(such as Console or Winform ), you will need to work with Automation API + Plugin API of Navisworks

if you wanted to build a plugin only, you will need to build a class, instead of Console or Winform or else.

if you wanted to build a standalone EXE program with Viewer, you will need to work with .NET Control API.

I would suggest you take a look at the basic tutorial of Navisworks API:
