You haven't shown the Save() method but if you can add code like this to it you'll get an exception that contains all the details you're looking for

try
{
    _context.SaveChanges();
}
catch (System.Data.Entity.Validation.DbEntityValidationException dbEx)
{
    Exception raise = dbEx;
    foreach (var validationErrors in dbEx.EntityValidationErrors)
    {
        foreach (var validationError in validationErrors.ValidationErrors)
        {
            string message = string.Format("{0}:{1}", 
                validationErrors.Entry.Entity.ToString(),
                validationError.ErrorMessage);
            // raise a new exception nesting
            // the current instance as InnerException
            raise = new InvalidOperationException(message, raise);
        }
    }
    throw raise;
}
