Hey guys,

I'm getting a problem in my project, before I upgrade my database to v12 my webapp worked perfectly, but after, every time that I execute query to show a column in a dropdownlist I receive this message "The data reader has more than one field. Multiple fields are not valid for EDM primitive or enumeration types.".

Someone had the same problem, or something like that?

Threre is my code.

    ApplicationDbContext context = new ApplicationDbContext();
    string user = User.Identity.GetUserId();

    System.Collections.Generic.List<SelectListItem> Devices = new System.Collections.Generic.List<SelectListItem>();

    var sqlcmd = "SELECT Nick FROM dbo.AspNetDevice WHERE OwnerID = '" + user + "' ORDER BY Nick ASC";
    context.Database.Connection.Open();
    try
    {
        var GetDevice = context.Database.SqlQuery<string>(sqlcmd);
        int count = GetDevice.Count(); int i = 0;
        if (count > 0)
        {
            Devices.Add(new SelectListItem { Text = "Selecione o Dispositivo", Selected = true, Disabled = true });
            while (i != count)
            {
                Devices.Add(new SelectListItem { Value = GetDevice.ElementAt(i), Text = GetDevice.ElementAt(i) });
                i++;
            }
        }else
        {
            Devices.Add(new SelectListItem { Text = "Adicione um Dispositivo", Selected = true, Disabled = true });
        }
    }
    finally
    {
        context.Database.Connection.Close();
    }
