He mentioned that they use the servicestack.text library. I've looked into servicestack recently (using the nuget packages), but then found the library to be pay-to-play. There's an older version (v3) that is BSD licensed that is being maintained. Do any of you have experience with it? I have grown tired of Microsoft pushing new solutions to the same problem (REST service with WCF and then Asp.net web api).
Technically we use Newtonsoft and Jil, Jil replacing Newtonsoft as we become increasingly confident in it.
I wouldn't suggest anyone use Jil in a production role unless you're at Stack Overflow. It's too untested at the moment, and the typical person can't get me on the horn to fix whatever just broke.
You wouldn't right now (Kevin doesn't recommend it). But in the end it you'll want to use it if JSON serialization is a performance bottleneck for you.
ServiceStack is just plain awesome when it comes to developing web services, though it's gone commercial for v4 onward. Nancy is another popular alternative - it's basically Sinatra for .Net. Every time I go back to WCF I want to stab myself in the face.
