基本上

在學習時看的文章，
都會在這邊放了個安裝檢測.net framework的方法
https://www.cnblogs.com/stoneniqiu/p/3380805.html

那我不免俗一起來一段安裝前檢測用法，
只是因為我們HelloWorld專案是用.Net Core的方式 !

而官方文件只有到4.6.2….

哈!好險我有找到使用 core 3.1 的使用方式
https://github.com/wixtoolset/issues/issues/6099

我們先加入參考檔案WixUtilExtension.dll

在Wix標籤的參考加入

xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"

然後Bundle標籤下面找個地方貼上

  <Fragment>
    <Variable Name="AspNetCoreRuntime31InstallDir" Value="[ProgramFiles64Folder]dotnet\shared\Microsoft.AspNetCore.App\3.1.0" />
    <util:DirectorySearch Id="AspNetCoreRuntime31Installed" Path="[AspNetCoreRuntime31InstallDir]" Variable="AspNetCoreRuntime31Installed" Result="exists" />

範例給了兩個抓Runtime部分的，我們只要用一個就可以了

• AspNetCoreRuntime31Web
• WindowsDesktopRuntime31Web

在Chain標籤內在我們主體安裝包前 貼上他的寫法

而他主要用的方法是去查看Microsoft.AspNetCore.App下有沒有建立這個3.1.0的資料夾

 <Variable Name="AspNetCoreRuntime31InstallDir" Value="[ProgramFiles64Folder]dotnet\shared\Microsoft.AspNetCore.App\3.1.0" />

我們建置後執行看看！↓↓↓

水唷! 可以看到打包檔就會先檢測有沒有Runtime，沒有了話會直接安裝Runtime3.1.0後，
才執行接下來主要的安裝包部分。

那因為這個是由網路下載的，
如果說有些公司有內外網分離的情況，
我們只好使用預先手動下載的方式，

先下載aspnetcore-runtime-3.1.0-win-x64.exe後放在程式內，
SourceFile指定位置↓↓↓

    <PackageGroup Id="AspNetCoreRuntime31Web">
      <ExePackage
          Name="aspnetcore-runtime-3.1.0-win-x64.exe"
          InstallCommand="/install /quiet /norestart /log "[AspNetCoreRuntime31Log]""
          RepairCommand="/repair /quiet /norestart /log "[AspNetCoreRuntime31Log]""
          UninstallCommand="/uninstall /quiet /norestart /log "[AspNetCoreRuntime31Log]""
          PerMachine="yes"
          DetectCondition="!(wix.AspNetCoreRuntime31WebDetectCondition)"
          InstallCondition="!(wix.AspNetCoreRuntime31WebInstallCondition)"
          Vital="yes"
          Permanent="yes"
          Protocol="burn"
          SourceFile="aspnetcore-runtime-3.1.0-win-x64.exe"
          LogPathVariable="AspNetCoreRuntime31Log"
          Compressed="yes">
      </ExePackage>
    </PackageGroup>

如果檔案想要附加在我們的Bootstrapper.exe
那Compressed 要改為 yes ，這樣檔案就會附加進去，
若沒有想要附加就維持 no，然後檔案屬性部分改成一律複製
最後移除掉整串RemotePayload 因為這個是由網址下載的情況才需要的。

建置後執行看看吧！

• 後記

我在這邊有測試過Runtime安裝，
基本上server 2019 2016 安裝上是沒問題，2012 必須升級到R2 才可以進行安裝，

然後像是我們的專案 CustomAction.dll，Framework是4.6.2的版本，
測試時我也有一併測試，
但exe檔包出來的安裝包，
基本上就不用擔心他有沒有Framework的問題，
所以就把檢測拔掉了XD
