I was following the instructions at https://our.umbraco.com/documentation/reference/using-ioc but without success.

As per the instructions I have created:

1. public class MyAwesomeContext
2. public class MyApplication : Umbraco.Web.UmbracoApplication
3. the Application tag inside the global.asax file in the web root
4. public class MyTestSurfaceController : SurfaceController

but I get internal server error

In the global file I register the controllers: var builder = new ContainerBuilder(); // register all controllers found in your assembly builder.RegisterControllers(typeof(MvcApplication).Assembly); builder.RegisterApiControllers(typeof(MvcApplication).Assembly);

builder.RegisterControllers(typeof(Umbraco.Web.UmbracoApplication).Assembly); builder.RegisterApiControllers(typeof(Umbraco.Web.UmbracoApplication).Assembly);

// add custom class to the container as Transient instance builder.RegisterType

var container = builder.Build(); DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); GlobalConfiguration.Configuration.DependencyResolver = new AutofacWebApiDependencyResolver(container);

but as soon as a call is added in the surfacecontroller to "public depinjController" it fails.

public class depinjController : SurfaceController { private readonly namespace.Utils.MyAwesomeContext _myAwesome;

    public depinjController(namespace.Utils.MyAwesomeContext myAwesome)
    {
        _myAwesome = myAwesome;
    }

    [ChildActionOnly]
    public ActionResult Index()
    {
        return Content("Hello World! Here is my id " + _myAwesome.MyId);
    }
}
