## What it is
PdfSharpCore is a .NET Standard port of the PdfSharp and MigraDoc libraries for creating and manipulating PDF documents, with GDI+ dependencies replaced by SixLabors ImageSharp and Fonts. It runs cross-platform on .NET Core, .NET 6+, and Xamarin.

## Use cases
- generate pdf files from .net core
- create pdf documents cross-platform in c#
- port pdfsharp code to .net standard
- draw text and images into a pdf programmatically
- generate pdfs in xamarin mobile apps
- replace gdi+ pdf generation with managed code

## When to choose
- you need to create or modify PDFs in .NET Core/.NET 5+ or Xamarin without Windows/GDI+ dependencies
- you want a managed, cross-platform port of PdfSharp/MigraDoc APIs

## When to avoid
- you need full PdfSharp feature parity, such as GetFontData or advanced font handling
- you need a commercially supported, fully stable PDF library
- you only target Windows with classic .NET Framework, where original PdfSharp works

## Facets
- artifact type: library
- maturity: active
- function: pdf, image-processing
- domain: pdf, files, cross-platform
- platform: dotnet, cross-platform
- tags: pdfsharp, migradoc, netstandard, pdf-generation, xamarin
