ASP.NET Core IHostedService + IIS自动启动功能不起作用

我有一个.NET 6 IHostedService托管在IIS 10 Windows Server 2019上。
我的目标是

在服务器重新启动后启动应用程序
iisreset后启动应用程序
iisreset /start后启动应用程序

我关注SO帖子here和这个博客post
关于SO post的回答：

我重启了服务器
遵循所有步骤

关于博客文章：

我尝试将CLR设置为“无托管代码”和“v4.0”

我在其他网站上发现了一些提到我必须启用匿名身份验证-这也是测试的（见下面的applicationhost.config）
但是我不能让IIS的这个基本功能启动和运行。根据SO帖子和博客帖子，它似乎帮助了大多数人。
web.config：

<?xml version="1.0" encoding="utf-8"?>

       <location path="." inheritInChildApplications="false">

您应该在服务器上启用Application Initialization模块以自动重新启动应用程序。
默认情况下，如果在20分钟内没有向应用程序发送请求，则应用程序将被挂起。

此PowerShell脚本可以帮助您保持应用程序始终处于活动状态

## IIS WebAdmin Module
    Import-Module WebAdministration

    $AppPoolInstance = Get-Item IIS:\AppPools\$AppPool

    Write-Output "Set Site PreLoadEnabled to true"
    Set-ItemProperty IIS:\Sites\$Site -name applicationDefaults.preloadEnabled -value True

    Write-Output "Set Recycling.periodicRestart.time  = 0"
    $AppPoolInstance.Recycling.periodicRestart.time = [TimeSpan]::Parse("0");
    $AppPoolInstance | Set-Item

    Write-Output "Set App Pool start up mode to AlwaysRunning"
    $AppPoolInstance.startMode = "alwaysrunning"

    Write-Output "Disable App Pool Idle Timeout"
    $AppPoolInstance.processModel.idleTimeout = [TimeSpan]::FromMinutes(0)
    $AppPoolInstance | Set-Item

    if ($appPoolStatus -ne "Started") {
        Write-Output "Starting App Pool"
        Start-WebAppPool $AppPool
    } else {
        Write-Output "Restarting App Pool"
        Restart-WebAppPool $AppPool
    }

- 注意：**您应该将$AppPool和$Site名称更改为您的应用程序
