Automatic Protocol Deserialization Using JSON Framework

Hey,

I'm trying to write a protocol parser in C# which would be simple to maintain.
My input is a Json payload, and I'm trying to convert it into a certain Request object in my inheritance-tree according to its identifier (which is obviously commonly named across all requests...).

I'm trying to come up with a way to parse this protocol without having a headache (if its possible).

I would be most grateful if somebody could offer me the lightest Json Deserialization Framework that will be able to support my needs.

My ultimate desires are rather simple.
I need to parse the identifier (obviously the whole object will be parsed already), and then, once I know the type I'm expecting, I could obtain the type (probably using enum attributes...), and reflect the rest of the object onto the type's format.

Are there even such frameworks that could help me accomplish my needs easily? Is there a better solution?

Thank you for reading, Your comments and suggestions are very welcome :)

I would say, this one:
http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer.aspx[^].

If helps you to serialize not just the object, but some arbitrary object graph. Also, it's totally non-intrusive. You only develop data types, with relationships between them (like compositions). Then you just add [DataContract] and [DataMember] attributes to what you need to be parts of the contract. You also have good provisions for backup compatibility, when you data model is evolved in newer versions of software, but the users still use persistent artifacts created by older version of software. And finally, this approach is the easiest to use. You never need to deal with JSON or XML directly, you only care about your data model, a set of pure data types.
