how to query many to many relationship in Linq to EF5 - asp.net

Question

I am learning EF5 and building a small website which simply displays some songs and singers. As a song can be sung by more than one singer and a singer will have many songs so my EF model as below.
I want to display all the list of songs with its relevant singers in a table so I wrote a query and this is so far I have.
Dim res = context.Songs _
.SelectMany(Function(song) song.Artists, Function(s, a) New With
{.SongTitle = s.SongTitle, _
.ArtistName = a.ArtistName, _
.Lyrics = s.Lyrics})
But I am having the result like below.
You will see Lucky is displayed twice in the table. I don't want that to happen. I just want to display it once but have join two singers in the Artist column. I tried to read tutorials and many forum posts but those tutorials don't get this complicated.
So how can i get change the query to return something like this?

Answer 1

I must write my answer with C#, hopefully you are able to translate it into VB.
I would do two changes:
First, simply use Select instead of SelectMany in this situation.
Second, introduce a named ViewModel instead of an anonymous type because it allows you to add a method or custom readonly property that will be helpful later.
The ViewModel would look like this:
public class SongViewModel
{
public string SongTitle { get; set; }
public string Lyrics { get; set; }
public IEnumerable<string> ArtistNames { get; set; }
public string ArtistNamesString
{
get { return string.Join(", ", ArtistNames); }
}
}
Then you can use this query:
var res = context.Songs.Select(s => new SongViewModel
{
SongTitle = s.SongTitle,
Lyrics = s.Lyrics,
ArtistNames = s.Artists.Select(a => a.ArtistName)
});
Now, to list the result, you can use a loop like this (example with console output):
foreach (var item in res)
{
Console.WriteLine(string.Format("{0} {1} {2}",
item.SongTitle, item.Lyrics, item.ArtistNamesString);
}
This lists each song only once and the artist names are displayed as a comma separated list.
