如果我像这样快速连续安装 IIS 服务器和托管包（在新的 Windows 10 服务器上）：

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

从安装的角度来看，一切都很好。但是，如果我在 IIS 中运行.NET Core 应用程序，则会发生以下错误：

谷歌搜索this happens when "Hosting Bundle is installed before IIS". The simple solution is written in the next sentence: "the bundle installation must be repaired"，这确实有效。

现在的问题是：

我如何完全避免这种情况？

或我如何等到 IIS 真的安装，所以它是安全的安装托管包？
