如果我像这样快速连续安装IIS服务器和托管捆绑包（在新的Windows 10 Server上）：

Install-WindowsFeature -Name Web-Server -IncludeAllSubFeature -IncludeManagementTools

# Ignore the next line for now, its my current workaround

Start-Sleep -Seconds 120

Write-Host "-- Installing Dotnet Hosting Bundle"
$ErrorActionPreference = "Stop";
$tempDir = [System.IO.Path]::GetTempPath()
$downloadPath = "$tempdir\netCoreHostingBundle.exe";
$DefaultProxy = [System.Net.WebRequest]::DefaultWebProxy;

$securityProtocol = @();
$securityProtocol += [Net.ServicePointManager]::SecurityProtocol;
$securityProtocol += [Net.SecurityProtocolType]::Tls12;
[Net.ServicePointManager]::SecurityProtocol = $securityProtocol;
$WebClient = New-Object Net.WebClient; 

$Uri = 'https://download.visualstudio.microsoft.com/download/pr/0d000d1b-89a4-4593-9708-eb5177777c64/cfb3d74447ac78defb1b66fd9b3f38e0/dotnet-hosting-6.0.6-win.exe';
if ($DefaultProxy -and (-not $DefaultProxy.IsBypassed($Uri))) { $WebClient.Proxy = New-Object Net.WebProxy($DefaultProxy.GetProxy($Uri).OriginalString, $True); };
$WebClient.DownloadFile($Uri, $downloadPath);

$arguments = New-Object -TypeName System.Collections.Generic.List[System.String]
$arguments.Add("/quiet")
$arguments.Add("/norestart")
Start-Process -FilePath $downloadPath -ArgumentList $arguments -NoNewWindow -Wait -PassThru -WorkingDirectory $tempDir

Write-Host "-- Restarting IIS"
Stop-Service W3SVC
Start-Service W3SVC
Get-Service W3SVC

从安装的Angular 来看，一切都很好。但是如果我在IIS中运行NET核心应用程序，则会出现以下错误：
HTTP Error 500.19 - HRESULT code 0x8007000d
在“Hosting Bundle is installed before IIS”（在IIS之前安装主机捆绑包）的情况下，谷歌搜索会发现这种情况。简单的解决方案写在下一句话中：“必须修复捆绑包安装”，这确实有效。
现在的问题是：

• 我该如何彻底扭转这种局面？
• 或者我如何等到IIS真正安装好，才能安全地安装托管包？
