JsonFx v2 is maintained over on GitHub

http://github.com/jsonfx/jsonfx

This repository remains as the source of JsonFx v1.

JsonFx is a fast Ajax framework for ASP.NET 2.0 and above:

• Supports true Ajax via client-side templating with familiar ASP-style syntax
• Supports JSON within all Ajax features
• JsonML+Browser-Side Templating (JBST) allows data-binding JSON in the client
• JSON-RPC 2.0 support with auto-generated JavaScript proxies
• Build-time optimization of client libraries (compaction/Gzip/Deflate)
• Build-time syntax checking of JavaScript & CSS
• Easily emit data into page as JavaScript
• Supports UserAgent-specific CSS (no more browser hacks)
• Dynamic behavior binding features
• Client-side globalization support
• Ajax history (browser back button) support
• Helps get a Grade A in YSlow

The JSON parser/serializer in JsonFx is able to be used outside of web apps:

• Functions similarly to the XmlSerializer in .NET
• Serializes and deserializes any Dictionary<String, T> and IDictionary with String keys directly as JSON objects
• Serializes and deserializes any List<T>, ArrayList, LinkedList<T>, Queue<T> and many other IEnumerable types directly as JSON arrays
• Serializes and deserializes DateTime, Enum, Nullable<T>, Guid and other common .NET Types directly as JSON primitives
• Serializes and deserializes strongly-typed custom classes (similarly to XML Serialization in .NET)
• Serializes C# 3.0 Anonymous Types directly as JSON objects
• Serializes C# 3.0 LINQ Queries as JSON arrays of objects (by enumerating the results)
• Optional ability to control serialization via attributes/interfaces
• Optional Type-Hinting improves deserializing to strongly-typed objects
• Optional PrettyPrint mode helps with debugging / human-readability
• Optional custom DateTime serialization override
• Optional native EcmaScript serialization of DateTime, Regex and identifiers
• Deserializes common non-JSON JavaScript literals such as "Infinity", "NaN", and "undefined"
• Ignores block and line comments when deserializing

The VSTemplates installer will add Visual Studio Project and Item Templates for the following:

• JsonFx-enabled ASP.NET MVC Application Project
• JsonFx-enabled ASP.NET Web Application Project
• JsonFx-enabled ASP.NET WebSite Project
• JBST Control Template
• JSON-RPC Service Template
• Merge File Template
