PDFsharp 6.5.0 final: .NET 8/9/10, .NET 4.6, NETstandard 2.0

[PDFsharp-Team]

Hello, everybody!

As of today, PDFsharp 6.5.0 final is available.

You can find the source code on github.com:
https://github.com/empira/PDFsharp

You can find binaries (assemblies) on NuGet.

Note: On NuGet there are Core, GDI, and WPF packages.

The six new NuGet packages:

• PDFsharp & MigraDoc Core: https://www.nuget.org/packages/PDFsharp-MigraDoc/6.5.0
• PDFsharp & MigraDoc GDI: https://www.nuget.org/packages/PDFsharp-MigraDoc-GDI/6.5.0
• PDFsharp & MigraDoc WPF: https://www.nuget.org/packages/PDFsharp-MigraDoc-WPF/6.5.0
• PDFsharp Core: https://www.nuget.org/packages/PDFsharp/6.5.0
• PDFsharp GDI: https://www.nuget.org/packages/PDFsharp-GDI/6.5.0
• PDFsharp WPF: https://www.nuget.org/packages/PDFsharp-WPF/6.5.0[/list]

All packages target .NET 8, .NET 9, and .NET 10 and can also be used with .NET 5 through .NET 7.
The Core packages also target .NET Standard 2.0 and should work with all compatible platforms including Windows and Linux.
The GDI and WPF packages also target .NET 4.6.2 and can also be used with higher versions like 4.7.2 or 4.8.1, but depend on Windows.

The source code is now compatible with Visual Studio 2026 with installed .NET 10 SDK.

Samples can be found on GitHub:

Changes since 6.2.4:

• Published under dual license: AGPL or optional commercial license
• Supports PDF dictionaries where the key is not a PDF name, but a string (improved compatibility with corrupted PDF files)
• Legacy support for ANSI-encoded PDF names
• More specific exceptions while decoding PNG files
• Signatures are now added with unique form object names

See here for details: http://docs.pdfsharp.net/General/History.html#ps-6-5-0

Changes since 6.2.3:

• Dependency on Microsoft.Extensions.Logging removed, the new version depends on "Microsoft.Extensions.Logging.Abstractions" instead. GitHub Use only M.E.L.Abstractions package instead of Microsoft.Extensions.Logging #325
• Optional /Length entry for encryption added always because Edge depends on it. GitHub UserPassword stopped working in 6.x series in Edge #261
• CArray now written with spaces. GitHub Serializing a CArray results in a broken document. #300
• JPEG issue resolved. GitHub PdfSharp fails to import a jpeg file - MoveToNextHeader moves over EOF #304, XImage.FromFile/FromStream throws InvalidOperationException (Unsupported image format.) for valid JPGs #309, XImage.FromFile/FromStream throws InvalidOperationException (Unsuported image format.) for valid JPGs. #310
• Indirect DecodeParms now handled correctly. GitHub Error 'System.InvalidOperationException: 'Byte[]' must not be null here.' #323
• MigraDoc shows filename in PDF if image cannot be found
• Fixed MigraDoc memory leak after rendering PDF; the last document remained in memory until a new document was rendered, but now it will be released immediately after rendering.

See here for details: http://docs.pdfsharp.net/General/History.html#ps-6-2-4

Changes since 6.2.2:

• Fixed bug with JPEG images from GDI images (GDI+ build only)

See here for details: http://docs.pdfsharp.net/General/History.html#ps-6-2-3

Changes since 6.2.1:

• Fixed bug with JPEG images from MemoryStream
• Fixed bug with duplicate IDs in object stream
• Fixed bug with signatures in DEBUG build

See here for details: http://docs.pdfsharp.net/General/History.html#ps-6-2-2

Changes since 6.2.0:

• New feature: Layout option when creating PDF files: Use "Verbose" to create readable PDF files for debugging, use "Compact" to get small files for production use.
• Resolved issue when encrypting certain files
• Fixed exception when opening files with 1030 bytes

Making major breaking changes in a minor version seems like a bad idea to me.

I appreciate that you want to get paid for your (excellent!) work. But a new minor version suddenly throwing a "license not found" exception is unexpected and annoying. This seems like the sort of change which should have required a bump in the major version number instead.

+1. I think it's a shame that so few companies give back, whole depending on FOSS, and think it's fine to try to get paid, but a license change should be a major version increment, IMO.

Major license change buried in the changelog for a new minor? Really?
