Hi

I have trouble with the latest version (7.7.6) of Umbraco and using Unity. If I have Unity enabled I get the following error in the Umbraco backend:

at System.Threading.Tasks.Task`1.GetResultCore(Boolean waitCompletionNotification)
   at Umbraco.Web.Editors.SectionController.GetSections()
   at lambda_method(Closure , Object , Object[] )
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass10.<GetExecutor>b__9(Object instance, Object[] methodParameters)
   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken)

If I disable Unity the backend works as expected. The Unity implementation worked fine in Umbraco v. 7.2.2 and earlier. I have followed the guideline at https://our.umbraco.org/Documentation/reference/using-ioc but I can't get the backend to work.

Any ideas of how to get things working? My Unity configuration looks like this right now. I've experimented with different techniques for loading all classes in different assemblies but without result.

public static void RegisterTypes(IUnityContainer container) {
                container.RegisterType<UmbracoContext>(
                    new PerHttpRequestLifeTime(),
                    new InjectionFactory(c => UmbracoContext.Current)
                );

                //container.RegisterTypes(AllClasses.FromLoadedAssemblies());
                //container.RegisterTypes(AppDomain.CurrentDomain.GetAssemblies().SelectMany(x => x.GetTypes()));
                container.RegisterType<LegacyTreeController>(new InjectionConstructor());

                container.RegisterType<ISettingsProvider, UmbracoSettingsProvider>(new PerHttpRequestLifeTime());
}

I hope there is someone who can give me at least a hint on where to look next. I've tried to follow the code into https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Web/Editors/SectionController.cs but without deeper knowledge of Umbraco foundation I get stuck very fast.
