  4. On the compile tab, click build events and paste this into Post-Build event (correcting paths as needed)

    copy $(TargetDir)"*.dll" "C:\Program Files\kma\Contensive\Addons"

  5. Add a reference to cpBase.dll -- usually found in c:\Program Files\kma\Contensive
  6. Paste the following code into the created class file.

    using System;
    using System.Collections.Generic;
    using System.Text;
    using Contensive.BaseClasses;

    namespace HelloWorldAddon
    public class helloWorld : Contensive.BaseClasses.AddonBaseClass
    // execute method is the only public
    public override object Execute(Contensive.BaseClasses.CPBaseClass cp)
    return "Hello World";

  7. Build the DLL. 
  8. Go to your admin site and open the navigator to Navigator >> Manage Addons >> Advanced >> click on Add-ons
