## Process ##

Create a new Controller:

<sxh csharp>
    //[BreezeController]
    public class MyController : ApiController
    {
        //Internal db which we do not expose:
        private TodoItemContext _dbContext = new TodoItemContext();

        public MyController() {}

        [HttpGet]
        public string Metadata() {
          //Expose our dto Context's metadata:
          return MyEFContextProvider.Metadata;
        }
        // ~/api/my/Todos
        [HttpGet]
        public IQueryable<Todo> Todos() {
            return _dbContext.Set<Models.TodoItem>().Select(x => new Todo {Id = x.TodoItemId, Name = x.Title});
        }

        [HttpPost]
        public SaveResult SaveChanges(JObject saveBundle) {
            return _contextProvider.SaveChanges(saveBundle);
        }
    }
</sxh>


Try hitting the `Todos` Action:

    http://localhost:56216/api/my/metadata



<WRAP tip>
If you get something akin to the following error:

<sxh>
Multiple actions were found that match the request: Metadata on type Spike.Controllers.MyController Todos on type Spike.Controllers.MyController
</sxh>

then you'll have to add an `{action}` to your routes:

<sxh CSharp>
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultActionApi",
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

</sxh>
</WRAP>

You should get something akin to:
