c# - C#UWP MediaPlayer在模拟器上崩溃

Question

我是UWP的新手，我尝试实例化MediaPlayer类。在本地计算机上，它可以正常工作，但在移动仿真器上会引发下一个异常:

An exception of type 'System.Runtime.InteropServices.COMException' occurred in project.exe but was not handled in user code

Additional information: ClassFactory cannot supply requested class (Exception from HRESULT: 0x80040111 (CLASS_E_CLASSNOTAVAILABLE))

堆栈跟踪:

• at System.StubHelpers.StubHelpers.GetWinRTFactoryObject(IntPtr pCPCMD)
• at Windows.Media.Playback.MediaPlayer..ctor()
• at Project.Services.PlaybackServiceFactory.Create(PlayerArgument arg)
• at Project.ViewModels.PlayerViewModel..ctor(PlayerArgument arg)
• at Project.MainPage.d__3.MoveNext()

使用MediaPlayer的所有uwp示例也会崩溃。以前工作正常，可能出什么问题了？我很乐意提供任何帮助，谢谢。

UPD:10.0.10586仿真器版本的实际问题

Answer 1

MediaPlayer constructor可从“通用发行版本10.0.14393.0”中获得。因此，请在14393仿真器或磨碎机中运行您的项目。

你可以dynamically detect features with API contracts (10 by 10)

The Universal Windows Platform (UWP) allows you to write your app once and target multiple device families, while also taking advantage of new APIs introduced on later versions of the OS as well as using unique APIs only present on certain device families.
