Json.NET

Json.NET is a popular high-performance JSON framework for .NET

Features

• Flexible JSON serializer for converting between .NET objects and JSON
• LINQ to JSON for manually reading and writing JSON
• High performance,faster than .NET's built-in JSON serializers
• Write indented,easy to read JSON
• Convert JSON to and from XML
• Supports .NET 2,.NET 3.5,.NET 4,Silverlight,Windows Phone and Windows 8 Metro.

The JSON serializer is a good choice when the JSON you are reading or writing maps closely to a .NET class.

LINQ to JSON is good for situations where you are only interested in getting values from JSON,you don't have a class to serialize or deserialize to,or the JSON is radically different from your class and you need to manually read and write from your objects.
