WebAPI and ODataController return 406 Not Acceptable

Question

Before adding OData to my project, my routes where set up like this:

       config.Routes.MapHttpRoute(
            name: \"ApiById\",
            routeTempl         


        

Answer 1

The problem/solution in my case was even more stupid. I'd left test code in my action that returned a completely different model type, just a Dictionary, and not my proper EDM model type.

Though I protest that the use of HTTP 406 Not Acceptable to communicate the error of my ways, is equally as stupid.
