A recent technical post explores a robust FFI (Foreign Function Interface) bridge between Rust and .NET 10, using the Oxigraph library as a case study. The approach leverages JSON serialization over raw C strings, opaque pointer handles to manage Rust objects from .NET, and GCHandle-pinned callbacks for event-driven communication. This pattern avoids complex marshaling code and keeps the interface simple and maintainable. For developers working on cross-language systems, this design offers a reusable template that balances performance with clarity. The post highlights how to structure Rust libraries for .NET consumption, including memory management and error handling across the boundary. As .NET 10 continues to evolve, such practical interop patterns become increasingly valuable for integrating high-performance Rust components into .NET ecosystems.
This article details a practical FFI bridge between Rust and .NET 10 using JSON over raw C strings, opaque pointer handles, and GCHandle-pinned callbacks. It demonstrates a clean, maintainable approach for cross-language interoperability that can be applied beyond the Oxigraph example.
