NCbor Serialization Library - Strategic Roadmap

Last Updated: 2025-06-23
Current Status: v1.0 PRODUCTION READY - STRATEGIC POSITIONING COMPLETE! 🎯

🎯 Strategic Vision: The System.Text.Json for CBOR

Based on comprehensive analysis from multiple AI models, this library is strategically positioned to become the modern, high-performance CBOR serialization standard for the .NET ecosystem. We are not just building another serialization library - we are establishing the future-aligned, AOT-first approach that follows Microsoft's architectural direction.
