fastJSON

JSON is a light-weight, language independent, data interchange format, a widely medium for data transfer in Web development.

At around 1200 lines of code, fastJSON is one of the most compact C# libraries for dealing with JSON, and one of the few that actually stay as close to the original JSON standard as possible.

fastJSON is extremely easy to use and comes with extensive documentation to help developers get started on their own projects and implementations.
