This is a complete, hands-on guide to converting HTML to PDF in C# with the SelectPdf library for .NET. It works up from a three-line conversion to a production-ready workflow: every one of the 19 code steps is a full, compiling example taken straight from this project and rendered with the Chromium engine, so the code you copy is code that actually runs. Along the way you will build a real invoice from a data model, render complex CSS and paginating tables, control layout, handle dynamic and authenticated pages, secure and archive your output, integrate with ASP.NET Core, and finish with notes on running in production and troubleshooting.
Getting started
Add the SelectPdf packages, then build and run:
dotnet add package Select.Pdf.NetCore
dotnet add package Select.Pdf.NetCore.Chromium.Windows
