Answer 1

Assuming that you have defined a relationship between PhotoAlbums and Photos in your DBML file, you can do this:

var albums = dataContext.PhotoAlbums.Select(album => new {
    AlbumId = album.AlbumId,
    Title = album.Title
    Date = album.Date,
    PhotoId = album.Photos.Select(photo => photo.PhotoId).FirstOrDefault()
});
