Selecting from Repository.All<T>() throws System.ArgumentException

[kayone]

This test exercises this issue

   GivenMovies();
   var item = _repo.All<Movie>().Select(c => new { title = c.Director.Name });
   item.ToList();

but calling to list that would convert the IQueryable to IList will resolve the issue.

   GivenMovies();
   var list = _repo.All<Movie>().ToList();
   list.Select(c => new { title = c.Director.Name });
   item.ToList();
