iTextSharp C# windows store application

Question

Before, I used ITextSharp to generate a PDF File in C# for Windows, and it worked perfectly, now that I need to compile it and run it in Windows store framework, i get errors: the major error comes from using System.IO.FileStream , which doesn't exist in windows store API, is there another type do the same as System.IO.FileStream in windows store app ? Here the code I used before :

     String mat;
        System.IO.FileStream fs;
        Document doc;
        mat = textBox1.Text;

       fs = new FileStream(mat + ".pdf", FileMode.Create, FileAccess.Write, FileShare.None);
           doc = new Document();
           PdfWriter writer = PdfWriter.GetInstance(doc, fs);
           doc.Open();
String texto = richTextBox1.Text;

           doc.Add(new Paragraph(texto));
doc.Close();

            this.Hide();

iTextSharp is not directly compatible with windows store apps, the conversion work is not that much but it's not done. Have a look at iTextSharp-Monotouch for a possible workaround.
