Orchardcms 1.6 IsScheduledTask-未再次创建任务

我有一个由任务调度器运行的服务方法。任务已创建并执行，但不会再次创建该任务。请参阅以下代码：

功能处理程序：任务在此处创建

public class NewsFeatureEventHandler : IFeatureEventHandler
{
    private const int TimeIntervalMinutes = 1;
    private const string TaskType = "Feeds";

    ...

    public void Enabled(Feature feature)
    {
        if (feature.Descriptor.Id.Equals("My.Module"))
            _taskManager.CreateTask(TaskType, DateTime.UtcNow.AddMinutes(TimeIntervalMinutes), null);
    }
    ...        
}

public class MyScheduledTaskHandler : IScheduledTaskHandler
{
private const int TimeIntervalMinutes = 1;
    private const string TaskType = "Feeds";

public void Process(ScheduledTaskContext context)
    {
    try
    {
        ...
    }
    catch
    {
    ...
    }
    finally
    {
        _taskManager.CreateTask(TaskType, DateTime.UtcNow.AddMinutes(TimeIntervalMinutes), null);
    }
}
}

ScheduledTaskHandler:任务在此处重新创建

public class NewsFeatureEventHandler : IFeatureEventHandler
{
    private const int TimeIntervalMinutes = 1;
    private const string TaskType = "Feeds";

    ...

    public void Enabled(Feature feature)
    {
        if (feature.Descriptor.Id.Equals("My.Module"))
            _taskManager.CreateTask(TaskType, DateTime.UtcNow.AddMinutes(TimeIntervalMinutes), null);
    }
    ...        
}

public class MyScheduledTaskHandler : IScheduledTaskHandler
{
private const int TimeIntervalMinutes = 1;
    private const string TaskType = "Feeds";

public void Process(ScheduledTaskContext context)
    {
    try
    {
        ...
    }
    catch
    {
    ...
    }
    finally
    {
        _taskManager.CreateTask(TaskType, DateTime.UtcNow.AddMinutes(TimeIntervalMinutes), null);
    }
}
}

你能看出上面的代码有什么问题吗。请给出一些建议和方向

关于这一点，

同样的问题已经在orchardpros.net上发布，与此无关。Mate你真的在使用1.6版吗？
