Question

Suppose I have a ASP.NET Web API controller that uses a service, which in turn depends on HttpControllerContext to perform some processing.

public class MyApiController : ApiController {

  IMyService _service;

  MyApiController(IMyService service) {
    _service = service;
  }

  public void Post(Resource resource) {
     _service.Process(resource);
  }
}

public interface IMyService {
  void Process(Resource resource);
}

public class MyService : IMyService {
  HttpControllerContext _controllerContext;

  MyService(HttpControllerContext controllerContext) {
    _controllerContext = controllerContext;
  }

  public void Process(Resource resource) {
     // use _controllerContext and process resource
  }
}

How does one configure Unity to inject an instance of HttpControllerContext when MyService is created? I am unable to find a way to get the HttpControllerContext used by the controller to be “injected” into the instance of MyService so it can use it.

Have a look at Mark Seemann’s post on how to wire HttpControllerContext with Castle Windsor. Unity should work similar.
