[MonoTouch] System.MissingMethodException: Method not found: 'System.Type.op_Equality'.

[ayoung]

json.net won't work on MonoTouch without some precompiler magic. Here's 4.0 r3 for MonoTouch https://github.com/ayoung/Newtonsoft.Json. 

Sebastien, is there some light reading on what smcs does? I did a quick search on the internets but didn't find much.
