Strongly-typed C# XML bindings for Transmodel-based European public transport standards. Currently, covers NeTEx (Network Timetable Exchange) and SIRI (Service Interface for Real-time Information), with the flexibility to support additional Transmodel-based standards.
Generated from the official CEN XSD schemas and verified with automated tests.
Note: This project was developed with significant AI assistance. While it is functional and tested, it has not yet undergone a full manual review. Treat it as pre-production. Cntributions and feedback are welcome.
A CLI tool that downloads XSD schemas from the official CEN repositories and generates modern C# XML bindings with the latest features. Use it to generate bindings for any schema version, including unreleased branches or specific commits.

If you don't need custom generation, install one of the pre-generated packages below. These are built with the same generator, tested, and published to NuGet for every release.
Versions correspond to tags in the NeTEx-CEN/NeTEx GitHub repository.

To build locally:
dotnet build Spillgebees.Transmodel.slnx --configuration Release
dotnet test --solution Spillgebees.Transmodel.slnx --configuration ReleaseThe build downloads the XSD schemas from GitHub, generates the XML bindings, and compiles them. Downloaded schemas are cached in local app data so subsequent builds don't require network access.
Use dotnet clean to remove the generated files and trigger a fresh generation on the next build.
