WiX v4 引导程序进程在安装结束后仍保持活动状态

问题描述 投票：0回答：1

我有一个 WiX v4 托管 BA，它有许多可再发行组件作为先决条件。安装完成并且所有内容都已成功安装，但即使在关闭 UI 并调用 Engine.Quit(0) 后，3 个引导程序进程也常常不会终止。可再发行安装程序成功退出，并且其日志中没有任何问题，因此我认为问题来自我的 BA。

在我的捆绑包中，我包含如下可再发行组件：

我的学士学位课程是：

using System.Windows.Threading;
using WixToolset.Mba.Core;

namespace Bootstrapper
{
    /// <summary>
    /// The custom bootstrapper application.
    /// </summary>
    public class CustomBA : BootstrapperApplication, ICustomBA
    {
#nullable enable

        public CustomBA(IEngine engine, IBootstrapperCommand command) : base(engine)
        {
            Engine = engine;
            Command = command;
        }

        /// <inheritdoc/>
        public IEngine Engine { get; set; }

        /// <inheritdoc/>
        public IBootstrapperCommand Command { get; set; }

        /// <summary>
        /// The global dispatcher.
        /// </summary>
        static public Dispatcher? BootstrapperDispatcher { get; private set; }

        /// <summary>
        /// The entry point for the custom UI.
        /// </summary>
        protected override void Run()
        {

            this.Engine.Log(LogLevel.Standard, "Launching custom bootstrapper UX");
            BootstrapperDispatcher = Dispatcher.CurrentDispatcher;

            MainWindowViewModel viewModel = new MainWindowViewModel(this);

            MainWindow view = new MainWindow();
            view.DataContext = viewModel;
            view.Closed += (sender, e) => BootstrapperDispatcher.InvokeShutdown();

            if (!viewModel.silent)
            {
                view.Show();
            }

            Dispatcher.Run();

            this.Engine.Quit(0);

        }
    }
}

从日志来看，BA 几乎在 Engine.Quit 之后执行清理之前就挂起了。

捆绑日志结尾为：

[098C:18D8][2024-07-31T13:40:42]i399: Apply complete, result: 0x0, restart: None, ba requested restart:  No
[098C:0B88][2024-07-31T13:45:23]i000: Dispatch complete, quitting engine. 
[098C:18D8][2024-07-31T13:45:23]i500: Shutting down, exit code: 0x0

而预期的台词后记是关于

Cleanup begin.
Cleanup not required due to running Apply.
Cleanup complete, result: 0x0
All the variable ending values blah blah
Exit code: 0x0, restarting: No

永远不要出现。

通常（并非总是）如果我在运行 BA 之前自行安装 NET 桌面运行时可再发行组件，进程会按预期终止并执行清理。

这种情况发生在全新安装时。 我可以看到没有待处理的重新启动或文件移动。 BA 没有遇到任何明显的异常或提供任何事件查看器信息。

在 Engine.Quit(0) 之后使用类似 Process.GetCurrentProcess().Kill(); 的方法自行终止进程；有效，但跳过了任何潜在的清理、关闭事件，总体感觉很恶心。

这不是 v3 中相同逻辑的问题，因此升级到 v4 的某些内容不正确，或者 v4 本身发生了行为更改（一些新的异步内容？），对此我无法追踪。

我可以根据要求提供任何其他日志或代码信息。

任何帮助，甚至左翼建议，将不胜感激:)

该问题是由于向 Engine.Apply 传递虚拟句柄而引起的。

 private void OnPlanComplete(object sender, PlanCompleteEventArgs e)
 {
     Bootstrapper.Engine.Log(LogLevel.Standard, $"Plan complete with status: {e.Status}");

     if (e.Status >= 0)
     {
         // Pass in a dummy handle since as of WiX v4, Apply no longer supports a handle of zero.
         // This handle is used for parenting Burn child UIs to the BA window, not needed for us.
         Bootstrapper.Engine.Apply(new System.Windows.Forms.Form().Handle);
     }
 }

如果没有真正的手柄，引擎（有时？？？？？？）在退出时似乎无法自行清理，即使安装顺利完成。

使用 

new WindowInteropHelper(this).EnsureHandle();
从 View 获取实际句柄并将其传递给 Apply，如下所示：

private void OnPlanComplete(object sender, PlanCompleteEventArgs e)
{
    Bootstrapper.Engine.Log(LogLevel.Standard, $"Plan complete with status: {e.Status}");

    if (e.Status >= 0)
    {
        // Use real window handle from the view.
        Bootstrapper.Engine.Log(LogLevel.Standard, $"Applying with window handle: {Bootstrapper.Handle}");
        Bootstrapper.Engine.Apply(Bootstrapper.Handle);
    }
}

为我解决了问题。
