Announcing WoofWare.PawPrint, a deterministic .NET runtime

▤ Summary

The article announces the early release of WoofWare.PawPrint to NuGet as a deterministic .NET runtime. The project interprets IL for .NET 10 and focuses on exploring thread interleavings to reproduce race conditions and deadlocks. It is designed for advanced debugging, provenance tracking, and eventual time-travel style analysis of execution history. The author also explains that the runtime is still incomplete and will likely fail quickly on real workloads because many native BCL behaviors are not yet modeled. The piece describes how LLMs helped accelerate development but also introduced architectural mistakes that required manual rewrites.
