hey,
I am creating MVC music store using MVC 4

I am getting an error while building app...
__'muzzicStore.Models.SampleData.seed(muzzicStore.Models.MusicStoreEntities)': no suitable method found to override D:\SHIVANI\MVC\muzzicStore\muzzicStore\Views\Models\SampleData.cs       muzzicStore____
my code is as follows:

protected override void seed(MusicStoreEntities context)
    {
        var genres = new List<Genre>
        {
            new Genre{Name="Rock"},
            new Genre { Name = "Jazz" },
            new Genre { Name = "Metal" },

        };

        var artists = new List<Artist>
        {
            new Artist { Name = "Aaron Copland & London Symphony Orchestra" },
            new Artist { Name = "Aaron Goldberg" },
};
        new List<Album>
        {
            new Album{Title="The best men at work",Genre=genres.Single(g=>g.Name=="Rock"),Price=8.98M,Artist=artists.Single(a=>a.Name=="Men At Work"),AlbumArtUrl="/Content/Images/placeholder.gif"},
             new Album { Title = "A Copland Celebration, Vol. I", Genre = genres.Single(g => g.Name == "Classical"), Price = 8.99M, Artist = artists.Single(a => a.Name == "Aaron Copland & London Symphony Orchestra"), AlbumArtUrl = "/Content/Images/placeholder.gif" },
 }.ForEach(a => context.Albums.Add(a));

    }

}
}

reply will be highly appreciable.
thanx and regards,
