EF Code First: How do I see 'EntityValidationErrors' property from the nuget package console?
Add-Migration "remigrate" ; Update-Database;

/// <summary>
/// Wrapper for SaveChanges adding the Validation Messages to the generated exception
/// </summary>
/// <param name="context">The context.</param>
private void SaveChanges(DbContext context)
{
    try
    {
    context.SaveChanges();
    }
    catch (DbEntityValidationException ex)
    {
    StringBuilder sb = new StringBuilder();

    foreach (var failure in ex.EntityValidationErrors)
    {
        sb.AppendFormat("{0} failed validationn", failure.Entry.Entity.GetType());

        foreach (var error in failure.ValidationErrors)
        {
        sb.AppendFormat("- {0} : {1}", error.PropertyName, error.ErrorMessage);
        sb.AppendLine();
        }
    }

    throw new DbEntityValidationException("Entity Validation Failed - errors follow:n" + sb.ToString());
    }
}
