Microsoft's MSBNx in C#

I need help getting to solve a compile error in C# using MS's MSBNx COM. I am using Visual Studio 2003 and C# 2005 Express. My goal is to manually add nodes to a MSBN3Lib.Model. I am able to load an existing file successfully with this method. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using MSBN3Lib; ....... private void button1_Click(object sender, EventArgs e) { MSBN3Lib.MSBN aMSBN = new MSBN3Lib.MSBN(); MSBN3Lib.Model model1 = aMSBN.Models.Add("Auto", @"C:Program FilesMSRASImsbnxSamplesNetworksauto.dsc", @"C:Program FilesMSRASImsbnxSamplesNetworkserrorfile.log", INFERENUM.ine_Default, RECOMMENDENUM.recommendtype_Default); axDgVw1.BeginInit(); axDgVw1.Model = model1; } THIS is the method I need help on. I can not get it to to compile succesfully and create the nodes. It seems that C# needs all of the arguments but I don't understand how to satisfy the requirenment. I am basically tring to rewrite this Visual Basic code from the example http://research.microsoft.com/adapt/MSBNx/msbn3/Overviews/Distributions.htm in C#. private void button2_Click(object sender, EventArgs e) { MSBN3Lib.MSBN aMSBN = new MSBN3Lib.MSBN(); MSBN3Lib.Model model1 = aMSBN.Models.Add(textbboxWord.Text, null, null, MSBN3Lib.INFERENUM.ine_Default, MSBN3Lib.RECOMMENDENUM.recommendtype_Default); MSBN3Lib.Node aNode; MSBN3Lib.Dist aDist; MSBN3Lib.Properties aProp; ************** Does not compile***************** aNode = model1.ModelNodes.Add("EngineStart", "Is engine started?", ref model1, ref model1, aDist, aProp); ************** Does not compile***************** //aNode.set_States("Working"); //aNode.set_States("Broken"); axDgVw1.BeginInit(); axDgVw1.Model = model1; } Can you make sure that it compiles for whom ever answers the question before posting an answer? Thank you very much.
