我想问你关于正确架构何时使用的意见Task.Run.我在WPF .NET 4.5应用程序(使用Caliburn Micro框架)中遇到了滞后的UI.

基本上我在做(非常简化的代码片段):

public class PageViewModel : IHandle<SomeMessage>
{
   ...

   public async void Handle(SomeMessage message)
   {
      ShowLoadingAnimation();

      // Makes UI very laggy, but still not dead
      await this.contentLoader.LoadContentAsync();

      HideLoadingAnimation();
   }
}

public class ContentLoader
{
    public async Task LoadContentAsync()
    {
        await DoCpuBoundWorkAsync();
        await DoIoBoundWorkAsync();
        await DoCpuBoundWorkAsync();

        // I am not really sure what all I can consider as CPU bound as slowing down the UI
        await DoSomeOtherWorkAsync();
    }
}

从我阅读/看到的文章/视频中,我知道await async不一定在后台线程上运行,并且需要在后台开始工作,需要等待它Task.Run(async () => …
