A while ago I mentioned how Orchard 1.6 will be running ASP.NET MVC 4, ASP.NET Web API, and NHibernate 3. I have already covered ASP.NET Web API in more detail in one of my ASP.NET MVC 4 Tutorials, ASP.NET MVC 4 Web API Routes and ApiController, but I thought I would at least give Web API a quick shoutout with Orchard CMS. As with all things Orchard, Web API works exactly as you would expect and can take advantage of the various services and extensions that come with Orchard.
