Hi, When using PDFSharp on Windows Azure Web Site, I got a System.OutOfMemoryException in the XGraphics.FromPdfPage(PDfPage) method. The system is not Under memory pressure during this problem. It works well if I execute this outside of Windows Azure Web Site. You cand find the stacktrace below: at System.Drawing.Graphics.FromHwndInternal(IntPtr hwnd) at System.Drawing.Graphics.FromHwnd(IntPtr hwnd) at PdfSharp.Drawing.XGraphics..ctor(PdfPage page, XGraphicsPdfPageOptions options, XGraphicsUnit pageUnit, XPageDirection pageDirection) at PdfSharp.Drawing.XGraphics.FromPdfPage(PdfPage page) at Alpha.Intra.Dossiers.Documents.BonCommande.GenerateDoc(PdfDocument document) in c:\code\Main\Alpha\Intra\Dossiers\Documents\BonCommande.ashx.cs:line 215 at Alpha.Intra.Dossiers.Documents.BonCommande.ProcessRequest(HttpContext context) in c:\code\Main\Alpha\Intra\Dossiers\Documents\BonCommande.ashx.cs:line 203 at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Do you have an idea of how to fix this? Thanks a lot. Regards Benjiiim |

Hi! Have you tried the WPF build instead of the GDI+ build? |

Thanks for your quick answer. I have not tried yet. Can I use the WPF build in an ASP.NET application? http://www.pdfsharp.net/NuGetPackage_PDFsharp-WPF.ashx states that "This build of PDFsharp is intended to be used in WPF desktop applications. In ASP.NET web applications PDFsharp (GDI) should be used." Thanks |

Hi Thomas, An other question: the Nuget package for the WPF version doesn't seem to be available. I can't find it on Nuget http://www.nuget.org/packages?q=PDFsharp Can you advise? Thanks a lot. |

You can find the binaries and the full source code on SourceForge or CodePlex. The WPF version is not yet on NuGet. I heard from Stefan that FromHwnd() is not working on Azure servers. He said he would look at it. He couldn't tell me whether the WPF build would work on Azure. |

Hi, I confirm that the root cause is on Windows Azure Web Site. Some System.Drawing features has been desactivated as they are not supported in a server environments. I have found and tried the WPF version yesterday and it works well, with no change in the code, which is great.  Having the WPF version on Nuget would be awesome. Thanks for the answers and for the great work you are doing on PDFSharp. Regards, |

Hi Thomas, I can see a PDFsharp-MigraDoc-WPF package on Nuget https://www.nuget.org/packages/PDFsharp-MigraDoc-WPF/ It doesn't seem to be an official package (not the same author). Is there a plan to create an official package? Thanks Regards, |

I'm trying to generate a PDF file in a web api hosted in Azure as an App Service. First, I was using PDFSharp and Mirgradoc and after reading this post I uninstall them to install PDFSharp Migradoc WPF as suggested in the discussion. Now, I'm getting this error message: "One or more errors occurred. (Could not load file or assembly 'PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.)". Is it possible to generate PDF files in an Azure App Services applications? What am I missing after installing the WPF version? |
