    I am fairly new to linq and ef, any help is appriciated.

    The query runs fine in Linqer but errors when I bind it to my listbox, I have added .ToList but I get the same results, it seems
    as though my query results is returning the wrong type.  I dont know what I am doing wrong with this query, below is the code

    ''Where Not In GenresMovieLink
           Dim qry = From genres In dbContext.Genres _
                Where _
                Not _
                (From genres0 In dbContext.Genres _
                 From movies In genres0.Movies _
                 Where _
                   CLng(movies.MovieID) = 19 _
                 Select genres0.GenreID).Contains(genres.GenreID) _
                Select _
                  genres.GenreID, _
           lbGenres.DataTextField = "Name"
           lbGenres.DataValueField = "GenreID"
           lbGenres.DataSource = qry.ToList

    Hi Daniel,

     This query does not seem wrong from the first sight but there is really no information for us to tell you if there is a problem and if the query is even executed against  OpenAccess of EF as mentioned in your ticket.
