description	Guidance for Microsoft Bond schematized data serialization framework. USE FOR: cross-platform schema-first serialization, Compact Binary and Fast Binary wire formats, schema evolution with backward/forward compatibility, high-performance RPC data contracts, strongly typed data interchange between .NET, C++, Python, and Java services. DO NOT USE FOR: JSON REST APIs (use System.Text.Json), human-readable config files, simple key-value storage, or when schema-less flexibility is required.

Bond

Overview

Bond is a cross-platform, schema-first serialization framework developed by Microsoft. It defines data schemas in files that are compiled into language-specific classes, supporting C#, C++, Python, and Java. Bond provides three binary protocols (Compact Binary, Fast Binary, and Simple Binary) and a JSON protocol. It excels in scenarios requiring high-performance serialization with schema evolution guarantees, making it popular in large-scale distributed systems at Microsoft. Bond handles schema versioning gracefully, allowing fields to be added or removed without breaking existing consumers.
