Add C# implementation with CI/CD infrastructure #13

konard · 2025-12-17T18:00:10Z

Summary

This PR adds full C# support to the lino-objects-codec library as requested in issue #9, along with complete CI/CD infrastructure following the patterns established for JS, Python, and Rust implementations.

Features Implemented:

ObjectCodec class with Encode() and Decode() methods
Basic types support: null, bool, int, long, float, double, string
Collection support: List<object?>, Dictionary<string, object?>
Circular reference support with preserved object identity
Base64 encoding for strings (full UTF-8 support)
Special float values: NaN, Infinity, -Infinity
Thread-safe static Codec class for easy access

Project Structure:

csharp/src/Lino.Objects.Codec/ - Main library
csharp/tests/Lino.Objects.Codec.Tests/ - Unit tests (69 tests)
csharp/examples/ - Usage example application
csharp/README.md - Documentation with API reference

CI/CD Infrastructure:

GitHub Workflow (csharp.yml):
- Lint job with format checking and warnings-as-errors build
- Multi-platform testing (Ubuntu, macOS, Windows)
- NuGet package building and artifact upload
- Changeset validation for PRs
- Automatic release on main push (when version changes)
- Manual release via workflow dispatch
Changeset System (csharp/.changeset/):
- README with instructions
- config.json for changeset configuration
Release Scripts (csharp/scripts/):
- create-github-release.mjs - Creates GitHub releases from CHANGELOG.md
- version-and-commit.mjs - Version bumping and commit automation
CHANGELOG.md for tracking version history

Repository-wide Updates:

Updated main README.md to include all 4 languages (Python, JavaScript, Rust, C#)
Merged changes from main branch including new JS/Python/Rust workflows
Removed old test.yml (replaced by language-specific workflows)
Now have 4 independent language workflows: js.yml, python.yml, rust.yml, csharp.yml

Test plan

All 69 C# unit tests pass locally
Example application runs without errors
Code formatting passes (dotnet format --verify-no-changes)
Build succeeds with warnings as errors
CI workflow runs successfully for C#
Documentation is complete and accurate

Changes from main branch merge

This PR incorporates changes from main including:

JavaScript CI/CD workflow and changeset infrastructure
Python CI/CD workflow and changelog.d infrastructure
Rust CI/CD workflow and changelog.d infrastructure
Various code quality improvements and formatting

Get latest changes from default branch. Resolve conflicts.

And also double check we fully support all best practices from templates:

Note that for each language we should have separate .changeset (or similar) folder.

But we can share .mjs scripts in root ./scripts folder if possible.

We should have no test.yml (it should be merged to the language versions), so end result would be 4 GitHub Workflows:

js.yml
python.yml
rust.yml
csharp.yml
