protobuf-net

Use "Protocol Buffers" serialization from your .NET code

Introduction

protocol buffers is the name of the binary serialization format used by Google for much of their data communications. It is designed to be:

• small in size - efficient data storage (far smaller than xml)
• cheap to process - both at the client and server
• platform independent - portable between different programming architectures
• extensible - to add new data to old messages

protobuf-net is a .NET implementation of this, allowing you to serialize your .NET objects efficiently and easily. It is compatible with most of the .NET family, including .NET 2.0/3.0/3.5, .NET CF 2.0/3.5, Mono 2.x, Silverlight 2, etc.
