Font data cannot be retrieved by PdfSharp / MigradDoc

I have an ASP.NET MVC web application and I am using PdfSharp / MigraDoc to generate reports. When I publish my app to azure and print the report, the following exception is thrown:

Internal error. Font data could not retrieved.

      

        
        
        
      

    

I have this method that determines the style of the report and I select the font Arial.

private void DefineStyle(Document document)
{
   Style style = document.Styles.AddStyle("Table", "Normal");
   style.Font.Name = "Arial";
   style.Font.Size = 9;
}

      

        
        
        
      

    

And in the last step, I render a PDF call to this method:

public void RenderAsPdf(Document document, HttpResponseBase response, string title)
{
        PdfDocumentRenderer renderer = new PdfDocumentRenderer(true, PdfSharp.Pdf.PdfFontEmbedding.Always);
        renderer.Document = document;
        renderer.RenderDocument();

        MemoryStream stream = new MemoryStream();
        renderer.Save(stream, false);

        response.Clear();
        response.AddHeader("Cache-Control", "no-cache");
        response.AddHeader("Pragma", "no-cache");
        response.ContentType = "application/pdf";
        response.AddHeader("Content-Disposition", "filename=" + title + ".pdf");
        response.AddHeader("content-length", stream.Length.ToString());
        response.BinaryWrite(stream.ToArray());
        response.Flush();
        stream.Close();
        response.End();
    }

      

        
        
        
      

    

This clause below throws an exception.

    renderer.RenderDocument();

      

        
        
        
      

    

I already fully trusted my application and didn't work. I added this config to web.config.

<configuration>
  <system.web>
   <trust level="Full" />
  </system.web>
</configuration>

      

        
        
        
      

    

I really don't know what to do ... How can I solve this? Thank!
