[C#] Errore FileIOPermission nell'accesso ad un file

[afrappe]

questo codice c# usa una libreria scritta in j# e dovrebbe generare un file pdf dandogli in pasto un file "xsl-fo"

ottengo questo errore alla riga
//setup output
OutputStream outfile = new FileOutputStream(pdf);

Richiesta di autorizzazione di tipo 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' non soddisfatta.

ho controllato la cartella dove è il file ".fo" ("c:\trasformazioni\test.fo"), ho everyone(fullcontroll),
ho aggiunto anche il mio utente e system per scrupolo ed ho assegnato anche ad essi il controllo completo della cartella
ma l'errore persiste. da cosa puo dipendere l'errore?



ecco il codice:

            //costruct driver
            Driver driver = new Driver();

            //setup logger
            Logger logger = new ConsoleLogger(ConsoleLogger.LEVEL_INFO);
            driver.setLogger(logger);
            MessageHandler.setScreenLogger(logger);
        
            //setup render(output format)
            driver.setRenderer(Driver.RENDER_PDF);
        
            //setup output
            OutputStream outfile = new FileOutputStream(pdf);
            try {
                driver.setOutputStream(outfile);
            
                //setup input
                InputStream infile = new FileInputStream(fo);
                
                try {
                    driver.setInputSource(new InputSource(infile));
                    //process FO
                    driver.run();
                }
                finally {
                    infile.close();
                }
            }
            finally {
                outfile.close();
            }
        
        }

        
        [STAThread]
        static void Main(string[] args)
        {
          

                Console.WriteLine("FOP ExampleFO2PDF\n");
                Console.WriteLine("Preparing...");
            
                                
                //setup input and output files
                string fofile = @"c:\trasformazioni\test.fo"; 
                string pdffile = @"c:\trasformazioni\result.pdf";

                Console.WriteLine("input: XSL-FO (" + fofile  + ")");
                Console.WriteLine("output: PDF (" + pdffile + ")");
                Console.WriteLine();
                Console.WriteLine("Trasforming...");

                ExampleFO2PDF.convertFO2PDF(fofile, pdffile);
                Console.WriteLine("Success!");
            
        
        }
    }
}

riporto anche lo stackTrace se puo servire a capire qualcosa

Non vorrei che la libreria e il programma tentassero inavvertitamente di aprire entrambi il file. Prova a vedere se riesci a passare alla libreria direttamente il percorso del file, escludendone l'apertura da programma.

Ciao!
