WinUI3 C++/WinRT应用关闭时FirstPage析构函数未调用问题

在Release模式下编译以下代码并运行，点击窗口的"X"按钮关闭应用后，发现FirstPage的析构函数并未被调用。

代码示例 #

1. App.xaml.cpp #

#include "pch.h"
#include "App.xaml.h"
#include "MainWindow.xaml.h"

using namespace winrt;
using namespace Windows::Foundation;
using namespace Microsoft::UI::Xaml;
using namespace Microsoft::UI::Xaml::Controls;
using namespace Microsoft::UI::Xaml::Navigation;
using namespace AppTest;
using namespace AppTest::implementation;

App::App()
{
    InitializeComponent();
}
void App::OnLaunched(LaunchActivatedEventArgs const&)
{
    window = make<MainWindow>();
    window.Activate();
}

2. MainWindow.xaml #

<Window
    x:Class="AppTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:AppTest"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <RelativePanel>
        <Frame Name="frameContent"/>
    </RelativePanel>
    
</Window>

3. MainWindow.xaml.cpp #

#include "pch.h"
#include "MainWindow.xaml.h"
#if __has_include("MainWindow.g.cpp")
#include "MainWindow.g.cpp"
#endif

#include "FirstPage.xaml.h"

using namespace winrt;
using namespace Microsoft::UI::Xaml;

namespace winrt::AppTest::implementation
{
    MainWindow::MainWindow()
    {
        InitializeComponent();
        this->frameContent().Navigate(winrt::xaml_typename<AppTest::FirstPage>());
    }
}

4. FirstPage.xaml.cpp #

#include "pch.h"
#include "FirstPage.xaml.h"
#if __has_include("FirstPage.g.cpp")
#include "FirstPage.g.cpp"
#endif

using namespace winrt;
using namespace Microsoft::UI::Xaml;

namespace winrt::AppTest::implementation
{
    FirstPage::FirstPage()
    {
        InitializeComponent();
    }
    FirstPage::~FirstPage()
    {
        /* 用于验证析构函数是否被调用的逻辑 */
    }
}

操作步骤 #

• 运行应用
• 点击窗口右上角的"X"按钮关闭应用

预期与实际结果 #

• 预期行为：FirstPage的析构函数应被调用
• 实际结果：FirstPage的析构函数未被调用
