" summary

Fluent Assertions is a C# test assertion library with about 244 million downloads that enforces API stability via a generated public API text file checked by Verify, runs Nuke build scripts and GitHub Actions for multi-targeted packages, and maintains roughly 25,000 unit tests plus benchmarks (BenchmarkDotNet) and analyzers to catch correctness and performance regressions. Documentation is Markdown-powered and published via Jekyll, release uses semantic versioning, NuGet prefix protection prevents impersonation, and the pipeline catches accidental breaking changes before release.
