使用Windows.media.miracast名称空间的正确方法是什么?

Question

我正在研究应用程序中通过Miracast铸造的屏幕，但不确定如何使用Windows.media.miracast名称空间。由于Windows 10 1903的更新，该名称空间是。

到目前为止，我唯一发现的就是此文档。

我的问题是有人知道使用此名称空间的正确方法是什么？在网上找到的任何示例或资源都将是一个很好的帮助。

欢呼。

这三个示例项目演示了可以从UWP应用程序中使用的各种奇迹源API。不确定外部UWP。

我个人在Windows Iot Core上使用以下代码来投射我的整个屏幕

扫描设备：

miraDeviceWatcher = DeviceInformation.CreateWatcher(CastingDevice.GetDeviceSelector(CastingPlaybackTypes.Video)); 
miraHandlerAdded = new TypedEventHandler<DeviceWatcher, DeviceInformation>(async (watcher, deviceInfo) =>
{
   await dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, async () =>
   {
      //Add each discovered device to our listbox
      CastingDevice addedDevice = await CastingDevice.FromIdAsync(deviceInfo.Id);
      var disp = new CastingDisplay(addedDevice); //my viewmodel
      MiraDevices.Add(disp); //ObservableCollection
   });
});
miraDeviceWatcher.Added += miraHandlerAdded;

连接到选定的设备：

public async Task StartCasting(CastingDisplay castee)
{
   //When a device is selected, first thing we do is stop the watcher so it's search doesn't conflict with streaming
   if (miraDeviceWatcher.Status != DeviceWatcherStatus.Stopped)
   {
      miraDeviceWatcher.Stop();
   }
   //Create a new casting connection to the device that's been selected
   connection = castee.Device.CreateCastingConnection();
   //Register for events
   connection.ErrorOccurred += Connection_ErrorOccurred;
   connection.StateChanged += Connection_StateChangedAsync;
   var image = new Windows.UI.Xaml.Controls.Image();
   await connection.RequestStartCastingAsync(image.GetAsCastingSource());
}

此图像只是用作铸造源。建立连接后，我的整个屏幕都会广播。行为没有记录。希望它在以后的更新中不会被"修复"。
