Error in API when creating user layer gfx?

I have created a C# console project in Visual Studio 2012. I am trying to create a circle on a user layer, but I keep getting the following error on the highlighed line below:

     An unhandled exception of type 'System.ArgumentException' occurred in System.Dynamic.dll

     Additional information: Could not convert argument 1 for call to PutUserLayerGfx.

I don't understand why it is trying to convert anything. All data types are correct and it compiles fine.

I have attached the entire VS solution. This is on Expedition 7.9.4, Windows 7 Enterprise 64bit. The solution is set to AnyCPU.


using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;


namespace PutUserLayerGfxTest


    class Program


        static void Main(string[] args)


            MGCPCB.Application pcbApp = (MGCPCB.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("MGCPCB.Application");

            MGCPCB.Document pcbDoc = pcbApp.ActiveDocument;

            pcbDoc.Validate(new MGCPCBAutomationLicensing.Application().GetToken(pcbDoc.Validate(0)));

            MGCPCB.UserLayer myLayer = null;

            myLayer = pcbDoc.FindUserLayer("MYLAYER");

            if (myLayer == null)

                myLayer = pcbDoc.SetupParameter.PutUserLayer("MYLAYER");

            dynamic pa = pcbApp.Utility.CreateCircleXYR(0.0, 0.0, 200.0);

            MGCPCB.UserLayerGfx gfx = pcbDoc.PutUserLayerGfx(myLayer, 0.0, 3, pa, false, null, MGCPCB.EPcbUnit.epcbUnitCurrent);

            if (gfx != null)
