问quartz.net何时使用JobBuilder.Create<>与JobBuilder.CreateForAsync<>()

EN

    public static JobBuilder Create<T>() where T : IJob
    {
        JobBuilder b = new JobBuilder();
        b.OfType(typeof(T));
        return b;
    }


    public static JobBuilder CreateForAsync<T>() where T : IJob
    {
        JobBuilder b = new JobBuilder();
        b.OfType(typeof(T));
        return b;
    }
