I am getting the following error:

** (ssis.exe:17939): WARNING **: string/stringbuilder marshalling conversion
29 not implemented

Unhandled Exception: System.NotImplementedException: string/stringbuilder
marshalling conversion 29 not implemented
  at (wrapper managed-to-native)
  at System.Runtime.Remoting.Proxies.RealProxy.GetTransparentProxy ()

  at (wrapper managed-to-native)
System.Object:__icall_wrapper_mono_object_new_specific (intptr)
  at Microsoft.SqlServer.Dts.Runtime.Application..ctor () [0x00000]

I had to copy the DLLs out of my development machine's GAC (it's a standard
windows development machine) for All of the SQL Server stuff to get to this

I am VERY new to mono, but have been developing on the .Net platform since
its inception, so please bear with my learning curve.

First, what does this error mean? And second, is there a resolution?

Here is the code that is running that produces the above error, it wsa
compiled on the Windows Dev box:

        static void Main(string[] args)
            Application app = new Application();
            MyEventListener eventListener = new MyEventListener();
            Package package = app.LoadPackage("test", eventListener);
            Variables vars = package.Variables;
            DTSExecResult result = package.Execute(null, null,
eventListener, null, null);

We are running mono 1.9.1 on a RHEL 5.3 x86_64 box.

Thanks in advance for any help,
Rob Weiss.
