Asp.net webapi error message

I have followed the WIKI trying to create a ASP.NET Web Api project with Owin.Scim.
Once running on localhost, the only endpoint that ASP.NET can discover is v2/resourcetypes. When trying to access this endpoint, i recieve the following error;
<Error> <Message>An error has occurred.</Message> <ExceptionMessage> An error occurred when trying to create a controller of type 'ResourceTypesController'. Make sure that the controller has a parameterless public constructor. </ExceptionMessage> <ExceptionType>System.InvalidOperationException</ExceptionType> <StackTrace> ved System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType) ved System.Web.Http.Controllers.HttpControllerDescriptor.CreateController(HttpRequestMessage request) ved System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__15.MoveNext() </StackTrace> <InnerException> <Message>An error has occurred.</Message> <ExceptionMessage> Typen 'Owin.Scim.v2.Endpoints.ResourceTypesController' har ikke en standardkonstruktør </ExceptionMessage> <ExceptionType>System.ArgumentException</ExceptionType> <StackTrace> ved System.Linq.Expressions.Expression.New(Type type) ved System.Web.Http.Internal.TypeActivator.Create[TBase](Type instanceType) ved System.Web.Http.Dispatcher.DefaultHttpControllerActivator.GetInstanceOrActivator(HttpRequestMessage request, Type controllerType, Func1& activator) ved System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)


`

All of the other endpoints (v2/Users, etc.) returns 404.

My Startup.cs looks like this;
` var config = new HttpConfiguration();

        config.Routes.MapHttpRoute(
            "DefaultApi",
            "api/{controller}/{id}",
            new { id = RouteParameter.Optional });

        var builder = new ContainerBuilder();
        builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
        builder.RegisterType<UserRepository>().AsSelf();
        builder.RegisterType<GroupRepository>().AsSelf();

        var container = builder.Build();
        config.DependencyResolver = new AutofacWebApiDependencyResolver(container);

        appBuilder.UseAutofacMiddleware(container);

        appBuilder.Map("/scim", app =>
        {
            app.UseScimServer(new Predicate<FileInfo>[] {fileInfo => fileInfo.Name.Equals("MyScimProject")},
                configuration =>
                {
                    configuration.RequireSsl = false; // disable SSL requirements
                    configuration.EnableEndpointAuthorization = false; // disable authentication requirements
                    configuration.DependencyResolver = new FuncDependencyResolver(type => container.Resolve(type));
                });
        });
        
        appBuilder.UseAutofacWebApi(config);
        appBuilder.UseWebApi(config);`

You should try append /scim at the beginning of your requests.
i.e:
/scim/v2/XXXX

I'm getting the same issue. In this case is with the UsersController as well, when I do /scim/v2/users

It happens with new implementation as well as the sample projects. Tried different nuget packages but all seem to have the same issue... Not sure why the internal IoC won't resolve the scim controllers.
