| Post subject: | .NET 8 AOT support |
Is it a hard task to get the PDFSharp to work with .NET 8 ahead-of-time (AOT) compiled to native code? It would be nice to generate PDFs with C# with a high performant self containd application. I have tried set the project property group <PublishAot>true</PublishAot> and publish an console application. It builds and publishes the files for win64 in my case with some trim warnings. When i creates a new PDFDocument in the code and it throwes the exception: Unhandled Exception: System.NotImplementedException: Cannot create value for key: /Info at PdfSharp.Pdf.PdfDictionary.DictionaryElements.GetValue(String, VCF) + 0x34d at PdfSharp.Pdf.Advanced.PdfTrailer.get_Info() + 0x20 at PdfSharp.Pdf.PdfDocument.get_Info() + 0x20 at PdfSharp.Pdf.PdfDocument..ctor(Stream) + 0x64 |

Creating a size-optimized self-contained package will not work as .NET removes too much code in the process. Maybe the same problem occurs with AOT. Try a variant that does not remove heuristically unused code if there is one. |

Thank you TH-Soft for your reply, I got it working by setting the property <TrimMode>partial</TrimMode>. As you saied it dident remove as much code but it works. Thanks! |

Setting `<TrimMode>partial</TrimMode>` worked for me. But using `<TrimmerRootAssembly Include="PdfSharp" />` instead also worked for me and the resulting .EXE was much smaller. Code: <PropertyGroup>
<OutputType>Exe</OutputType> <TargetFramework>net8.0</TargetFramework> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <PublishAot>true</PublishAot> <PublishTrimmed>true</PublishTrimmed> <!--<TrimMode>partial</TrimMode>--> <InvariantGlobalization>true</InvariantGlobalization> </PropertyGroup> <ItemGroup> <TrimmerRootAssembly Include="PdfSharp" /> </ItemGroup> |
