Greetings,

I was just studying an advanced robotic webinair named "Importing Custom DLL files". I made a very simple DLL (Class module in .NET speak) wiht just one class and one method and tried to import that DLL as a cuctom DLL. See code below:

namespace AdvCustomDLL
{
  public class Hello
  {
    public string World()
    {
      return ("Hello World!");
    }
  }
}

When trying to insert this DLL using "Choose Toolbox Items", "Browse" the result is a No Go. See attached screen shot.

So this brings me to the questions:

Do custom DLL's need a specific interface and/or structure?

If Yes what and how? Where can I find more information?

I'm using Pega Robotics Studio version 8.0.1081.0.

The small test mentioned above is made with Visual Studio 2017 with Target Franework 4.5.2. Any CPU.

Hope to hear, Aad Slingerland.
