c# - WPF 应用程序的 AppDomain ExecuteAssembly 按预期关闭

Question

我在后台线程中使用 API“ExecuteAssembly”在辅助 AppDomain 中启动 WPF 应用程序。当这个辅助应用程序关闭时（例如用户关闭主窗口），我发现正常的关闭序列不会像应用程序在独立的 AppDomain 中运行时那样被执行。具体来说，Application类的OnExit方法没有被调用。

有人遇到过这种情况么？

例如启动我的辅助 appdomain

        var thread = new Thread(() =>
        {
            var currentAppDomain = Thread.GetDomain();
            try
            {
                // line below blocks until complete
                currentAppDomain.ExecuteAssembly("PathToAssemblyToExecute");
                // at this point, executing assembly has been closed
            }
            catch (ThreadAbortException)
            {
                // do nothing.  this can occur due to timing issues.  framework seems
                // to send this exception out when unloading an appdomain
            }
            catch (Exception)
            {
                // an unhandled exception has occured in this app                                        
                AppDomain.Unload(currentAppDomain);
            }
        });
        thread.SetApartmentState(ApartmentState.STA);
        thread.Start();
