Dealing with challenges in resolving controllers with AngularJS and TypeScript

Getting an error with this script:

https://gist.github.com/whisher/6231714

The error I'm encountering is: Unknown provider: albumsProvider <- albums

this.app.config(($routeProvider:ng.RouteProvider) => { 
            $routeProvider.
                    when('/', {
                        templateUrl: './view.html', 
                        resolve: {
                            albums: function(Album) {
                               console.log(Album);
                                return Album.getResource().query();
                            }
                        },
                        controller: 'AlbumController',
                        })

           } ); 
class AlbumController {
    constructor (private $scope,private albums) {
        this.$scope.test = '20 whatsomething';
        this.$scope.albums = albums;
    }
}

I have checked that Album is in the scope using console.log(Album); However, I am only getting the above error instead of the desired albums.

I'm not sure which direction to take next. Any hints or suggestions would be appreciated!

Thank you.

Revised Response: Angular has a limitation when it comes to dependency injection - you can only inject items that have been registered with it. In your case, by using

this.app.service ('Album',Album);

You are limiting the ability to request Album only and not album. Therefore, it's necessary to make an adjustment in your constructor from:

constructor (private $scope,private albums) {
    this.$scope.test = '20 whatsomething';
    this.$scope.albums = albums;
}

to:

// Only variables registered with angular can be injected:
constructor (private $scope,private Album) {
    this.$scope.test = '20 whatsomething';

    this.$scope.albums = Album.getResource(). /* Make requests based on http://docs.angularjs.org/api/ngResource.$resource */
}
