启动条件、自定义操作和属性

Question

wix 安装程序没有安装我们的应用程序 IISversion >=10。它适用于 IISVersion

我在 github 上找到了这个链接。 https://github.com/wixtoolset/issues/issues/5276 此链接建议添加一个自定义操作，如果 IISRegistryversion >= IISRequiredVersion，则返回 ActionResult.Success。 但我收到以下错误。错误发生在日志中之后 执行操作：LaunchConditions

动作开始时间 12:46:02：LaunchConditions。 未设置变量或未调用自定义操作。 我在自定义操作中有一些日志记录，但即使打开了详细信息，它也没有记录任何内容。

如何确保在评估此条件之前调用了启动条件/自定义操作？谁能推荐一下？

这是 Product.wxs 的样子

            bool isRequiredVersion = iisMajorVersion >= IisRequiredVersion;

            // Setting the required version as a custom property, so that it can be used in the condition message
            session["IIs.RequiredVersion"] = IisRequiredVersion.ToString(CultureInfo.InvariantCulture);
            // Setting the results of the check as "bool"
            session["Iis.IsRequiredVersion"] = isRequiredVersion ? "1" : "0";

            return ActionResult.Success;
        }
        catch (Exception ex)
        {

            return ActionResult.Failure;

    }

它可以在没有条件的情况下工作。条件在

之前执行

功能检查 Feature.WebServer.WebServices = 3 不起作用，因为在计算成本（并且通常在功能对话框中选择功能）之后才设置“待安装”功能状态。所以没有调用 CA。

您可能需要重新考虑这一点并在 CostFinalize 之后强制检查 IIS，然后可能会警告 IIS 未安装/运行等。因此，您将无条件搜索 IIS 以设置属性而不使用它作为启动条件。如果 &Feature.WebServer.WebServices = 3 并且 IIS 版本太低，则给出警告。

请参阅功能操作条件文档和对 CostFinalize 的参考：
