推荐答案

它们仍然适用于 Windows Phone 8.1 SIlverlight 应用程序，但不适用于 Windows Phone 商店应用程序.Windows 应用商店应用的替代品是:

They still exists for Windows Phone 8.1 SIlverlight Apps, but not for Windows Phone Store Apps. The replacements for Windows Store Apps is:

Sleep(参见 Windows Store .NET 中的 Thread.Sleep 替换):

Sleep (see Thread.Sleep replacement in .NET for Windows Store):

await System.Threading.Tasks.Task.Delay(TimeSpan.FromSeconds(30));

Dispatcher(参见如何部署.Current.Dispatcher.BeginInvoke 在 Windows 商店应用程序中工作?):

Dispatcher (see How the Deployment.Current.Dispatcher.BeginInvoke work in windows store app?):

CoreDispatcher dispatcher = CoreWindow.GetForCurrentThread().Dispatcher;
await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { });
