windows - 当另一个AppWindow在第二个监视器上进入Fullscreen时，如何使UWP AppWindow保持全屏显示？

Question

我试图在全屏的单独显示器上打开2个AppWindows(appWindowOne和appWindowTwo)，但是当appWindowTwo打开时，appWindowOne会最小化。我尝试以编程方式使AppWindow重新进入全屏状态，但它会使其他AppWindow最小化。当在任务栏中手动单击时，它会恢复为全屏显示，而不会影响其他屏幕，但是我想知道是否可以通过编程方式进行？

public static async void ShowAppWindows()
{
    AppWindow appWindowOne = await AppWindow.TryCreateAsync();
    Frame frameOne = new Frame();
    ElementCompositionPreview.SetAppWindowContent(appWindowOne, frameOne);

    AppWindow appWindowTwo = await AppWindow.TryCreateAsync();
    Frame frameTwo = new Frame();
    ElementCompositionPreview.SetAppWindowContent(appWindowTwo, frameTwo);

    FullScreenPresentationConfiguration FSPC = new FullScreenPresentationConfiguration()
    {
         IsExclusive = false
    };

    await appWindowOne.TryShowAsync();
    appWindowOne.RequestMoveToDisplayRegion(displayRegions[0]);
    appWindowOne.Presenter.RequestPresentation(FSPC);

    await appWindowTwo.TryShowAsync();
    appWindowTwo.RequestMoveToDisplayRegion(displayRegions[1]);
    appWindowTwo.Presenter.RequestPresentation(FSPC);
}

. I've tried making the AppWindow re-enter full screen programmatically but it causes the other AppWindow to minimize.

当使 appWindowTwo进入全屏显示时，UI线程已损坏。我猜想在全屏中连续设置两个窗口会耗尽UI线程。因此，我们可以在将 Task.Delay()变成全屏之前尝试调用 appWindowTwo。
