Linq: C# to VB conversion help needed

[JumpyNET]

I am trying to convert the C# LongListSelectorSample from http://phone.codeplex.com/ to VisualBasic.

 

Here is the original C# code (with the problematic linq-query included):

       private void LoadLinqMovies()
       {
           List<Movie> movies = new List<Movie>();

           for (int i = 0; i < 50; ++i)
           {
               movies.Add(Movie.CreateRandom());
           }

           var moviesByCategory = from movie in movies
                                  group movie by movie.Category into c
                                  orderby c.Key
                                  select new PublicGrouping<string, Movie>(c);

           linqMovies.ItemsSource = moviesByCategory;
       }

 

And here is my VB attempt to populate the LongListSelector with grouped movie items:

   Private Sub LoadLinqMovies()
       Dim MovieList As New List(Of Movie)

       For i As Integer = 0 To 49
           MovieList.Add(Movie.CreateRandom())
       Next

       Dim MoviesByCategory = _
                      From OneMovie In MovieList _
                      Group OneMovie By Cat = OneMovie.Category _
                      Into GroupedMovies = Group _
                      Select New PublicGrouping(Of String, Movie)(GroupedMovies)

       Movies_LLS.ItemsSource = MoviesByCategory
   End Sub

Apparently something goes wrong with the linq query but what?
