Can I do a subquery in in SELECT of LINQ to Entities to fill List in model?

Is it possible to have a subquery in the .Select part of a LINQ to Entities query in order to fill a List<string> inside my view model? I found Use Linq To Entities subquery within Select clause to fetch a field value but when I try to do that I am getting the error:

NotImplementedException: Microsoft.Data.Entity.Query.ResultOperators.Internal.QueryAnnotationResultOperator

Is this possible to do with Entity Framework 7 and ASP.Net 5 MVC 6?

var model = _DbContext.ReleaseVersions
                        .OrderByDescending(rv => rv.DateReleased)
                        .Select(rv => new ReleaseNotesVM()
                        {
                            ID = rv.ID,
                            CurrentVersion = string.Concat(rv.Major, '.', rv.Minor, '.', rv.Patch),
                            ReleaseNotes = _DbContext.ReleaseNotes
                                                    .Where(rn => rn.ReleaseVersionID == rv.ID)
                                                    .Include(rn => rn.ReleaseVersion)
                                                    .Select(rn => rn.Note)
                                                    .ToList()
                        }).FirstOrDefault();

ViewModel being filled:

public class ReleaseNotesVM
{
    public byte ID { get; set; }
    public string CurrentVersion { get; set; }
    public DateTime CurrentVersionReleaseDate { get; set; }
    public IEnumerable<SelectListItem> VersionList { get; set; }
    public byte SelectedVersionID { get; set; }
    public ICollection<string> ReleaseNotes { get; set; }
}

DataModel:

public class ReleaseVersion
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public byte ID { get; set; }

    public DateTime DateReleased { get; set; }
    public byte Major { get; set; }
    public byte Minor { get; set; }
    public byte Patch { get; set; }

    public virtual ICollection<ReleaseNote> ReleaseNotes { get; set; }
}
public class ReleaseNote
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int ID { get; set; }

    public string Note { get; set; }
    public byte ReleaseVersionID { get; set; }

    [ForeignKey("ReleaseVersionID")]
    public ReleaseVersion ReleaseVersion { get; set; }
}
