Ага
По ссылке fed даже примерчик небольшой есть для вызова статического метода

using System;
using Bcn = Microsoft.Dynamics.BusinessConnectorNet;
class DemoCallXppFromCSharp
{
    public static void Main()
    {
        bool boolStringsSame;
        Bcn.Axapta axp;
        axp = new Bcn.Axapta();
        try
        {
            axp.Logon(null, null, null, null);
        }
        catch (Exception excepn)
        {
            Console.WriteLine(excepn.ToString());
            return;
        }
        boolStringsSame = axp.CallStaticClassMethod
            ("DemoBcnClass", // The class name.
            "AreStringsTheSameMethod", // The method being called.
            "H64", "L8"); // These two strings are not the same.
        Console.WriteLine(boolStringsSame);
        }
    }
}
