protobuf-net by: Marc Gravell

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 2.0/3.0/3.5/4.0, .NET CF 2.0/3.5, Mono 2.x, Silverlight, etc.

Respond by: Scott Jehl Paul Irish Nicholas Zakas

The goal of this script is to provide a fast and lightweight (3kb minified / 1kb gzipped) script to enable responsive web designs in browsers that don't support CSS3 Media Queries - in particular, Internet Explorer 8 and under. It's written in such a way that it will probably patch support for other non-supporting browsers as well (more information on that soon).
