NinjaBone is a project mainly written in JAVASCRIPT and C#, it's free.
This project started with inspiration of NinjaBone but the main goal was to see if it's possible to build an mobile application driven by a REST service with jquery template. I'm not sure that this is the prefered way so the main goal for me right now is to use the application for some experiment. The UI, javascript integration and the test is crap but there are some things that I do like.
Service Stack is a modern, code-first, DTO-driven, WCF replacement web services framework encouraging best-practices for creating DRY, high-perfomance, scalable REST web services
NOTE I replaced the dependency injection of Service Stack with AutoFac as a proof of concept and it was pretty easy as long as the ServiceHost is internal
The REST implementation is located under NinjaBone.Api
Example of hello world using ServiceStack
Autofac is an IoC container for Microsoft .NET. It manages the dependencies between classes so that applications stay easy to change as they grow in size and complexity. This is achieved by treating regular .NET classes as components.
mvc-mini-profiler is a simple but effective mini-profiler for ASP.NET MVC and ASP.NET.
I don't think that this profile will replace profilers like Uberproof or .dottrace but it give a quick hint if the page is kosher.
