What’s new

See History for information about all changes.

Prerequisites

What you need to use PDFsharp 7.0.0 Preview 1.

  • NuGet packages targeting .NET 8, .NET 9, .NET 10, .NET Standard 2.0, and .NET 4.6.2
    For your .NET (former .NET Core) projects, our NuGet packages target .NET 8 and higher. For WinForms (GDI+) or WPF projects under .NET, our packages target .NET 8 and higher for Windows.
    For your .NET Framework projects, our packages target .NET Standard 2.0. For WinForms (GDI+) or WPF projects, our packages target .NET Framework 4.6.2.

  • Latest SDK for building PDFsharp solutions
    Use the latest version of the SDK (.NET 10.0.100) to build the PDFsharp solution. This is because we use C# features from versions higher than C# 7.

Breaking changes

There are breaking changes in PDFsharp 7.0 relative to 6.x.
See History for information about all breaking changes.

For information about the transition from PDFsharp 1.5 or PdfSharpCore 1.3 to PDFsharp 7 see Upgrade to PDFsharp 6.

Assets are removed from repositories

PDFsharp uses a lot of assets like files for images, fonts, or PDFs. Starting with PDFsharp 6 these assets are not part of the repositories anymore. Instead, they are available for download from https://assets.pdfsharp.com. Before you can compile or run projects of a solution go to the dev folder in the solution root and run download-assets.ps1 once. This script downloads the assets required by the solution from the web into the assets folder.

Compile PDFsharp solutions

When you clone a repository like PDFsharp or PDFsharp.Samples from GitHub and download the assets once, it should compile immediately with Visual Studio or dotnet build.

  • A C# file may contain non-ASCII characters and have neither BOM nor UTF-8 encoding. This can happen because our German Windows machines may encode such a file with Western European Codepage 1252 and such a file cannot be opened correctly on e.g. a Chinese Windows machine. Maybe this issue is already fixed in Visual Studio.

Let us know when a solution does not compile immediately.

Running tests

Run examples under Linux

The PDFsharp solution builds completely under Linux. But obviously only the PDFsharp core examples can be executed. We test it using WSL2 with Ubuntu 20.04 LTS.
