c# - Rx 调度程序选项已弃用

Question

我正在尝试开始使用 Reactive Extensions (Rx)。这是我编造的一个小例子:

        var query = from number in Enumerable.Range(1, 20) select number;
        var obs = query.ToObservable(Scheduler.ThreadPool);

        obs.Subscribe(Console.WriteLine);

        Console.ReadLine();

当我使用 Scheduler.ThreadPool、Scheduler.NewThread 等时，我收到此警告:

System.Reactive.Concurrency.Scheduler.ThreadPool' is obsolete: 'This property is no longer supported due to refactoring of the API surface and elimination of platform-specific dependencies. Consider using Scheduler.Default to obtain the platform's most appropriate pool-based scheduler. In order to access a specific pool-based scheduler, please add a reference to the System.Reactive.PlatformServices assembly for your target platform and use the appropriate scheduler in the System.Reactive.Concurrency namespace. See http://go.microsoft.com/fwlink/?LinkID=260866 for more information.

如果我按照警告的说明进行操作，我仍然会收到警告。如果我想使用过去可通过 Scheduler 类获得的各种选项，我究竟应该为调度程序使用什么？

大多数调度器都应该有一个默认实例。您应该能够使用 NewThreadScheduler.Default、ThreadPoolScheduler.Instance 等
