.Net Core 8.0 ShadowCopy 設定介紹

ASP.NET Core 部署至 IIS ， *.dll 檔案會被鎖定，導致這些檔案無法順利更新，必須暫時關閉應用程式集區才能順利對網站進行部署

舊版本可以利用app_offline.htm，但 *.dll不會馬上解除鎖定

web.config 範例配置:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\Test.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout">
        <handlerSettings>
          <handlerSetting name="enableShadowCopy" value="true" />
          <handlerSetting name="shadowCopyDirectory" value="./ShadowCopyDirectory/" />
          <!-- Only enable handler logging if you encounter issues-->
          <handlerSetting name="debugFile" value="./ShadowCopyLogs/aspnetcore-debug.log" />
          <handlerSetting name="debugLevel" value="FILE,TRACE" />
        </handlerSettings>
      </aspNetCore>
    </system.webServer>
  </location>
</configuration>

注意事項:

1. Log不要放在同WebSite資料夾內，shadowCopy也會整個複製，導致容量過大
