如何在使用 WiX Burn MBA Bundles 的 MajorUpgrade 期间检测当前安装的功能？

Question

我正在使用 WiX 3.7 的 Burn/Managed Bootstrapper Application 功能来创建基于 MBA 的自定义安装程序。对于我的包链中的每个包，在执行 MinorUpdate 时，我可以轻松检测哪些包功能已安装，以确保在升级期间通过使用引导程序的 WiX 基类中提供的这些事件来维护这些功能选择：DetectPackageComplete、DetectMsiFeature、DetectRelatedBundle、DetectRelatedMsiPackage、DetectComplete。

但是，在 MajorUpgrade 期间，我只看到了一种确定安装了哪些软件包的方法，但没有看到如何确定安装了哪些功能，因为 DetectMsiFeature 事件不会触发。 我尝试在产品配置上使用MigrateFeatures 标志，但这似乎不起作用（或者我没有正确使用它）。

在 WiX 中使用自定义托管引导程序应用程序执行 MajorUpgrade 时，检测/迁移现有功能的正确方法是什么？

我将Bob Arnson's response 标记为答案，因为它为我提供了推动这一进程所需的东西，但对于遇到这篇文章的其他人，我想我会提供更多关于如何收集的细节该功能状态使用 WiX 提供的 ProductInstallation 类（在 WiX SDK 中的 Microsoft.Deployment.WindowsInstaller.dll 程序集中找到），因此无需直接调用本机 MSI API。

这是一个可以注册到DetectRelatedMsiPackage 事件的方法示例。请注意，您需要存储所收集的信息，以便在计划阶段设置适当的状态。

private void DetectRelatedMsiPackageHandler(object sender, DetectRelatedMsiPackageEventArgs e)
{
    var existingPackageProductCode = e.ProductCode;
    var actionToBeAppliedToExistingPackage = e.Operation;
    var existingPackageId = e.PackageId;
    var existingPackageVersion = e.Version;

    Log(string.Format("Detected existing related package {0} (product: {1}) at version {2}, which will be {3}",
                      existingPackageId, existingPackageProductCode, existingPackageVersion,
                      actionToBeAppliedToExistingPackage));

    if (actionToBeAppliedToExistingPackage == RelatedOperation.MajorUpgrade)
    {

        //requires reference to WiX Toolset\SDK\Microsoft.Deployment.WindowsInstaller.dll
        var installedPackage = new Microsoft.Deployment.WindowsInstaller.ProductInstallation(existingPackageProductCode);
        if (!installedPackage.IsInstalled) {
            Log(string.Format("Migrating Package {0}, which is not installed, so marking it and it's features as Absent", existingPackageId));
            //TODO: add logic to store state so that during Plan phase can set package with package with product code = existingPackageProductCode to PackageState.Absent
        } else {
            Log(string.Format("Migrating features for MajorUpgrade of Package {0}", existingPackageId));

            foreach (var currentInstallFeature in installedPackage.Features) {                        
                if (currentInstallFeature.State == InstallState.Local) {
                    Log(string.Format("Migrating feature {1} of Package {0} - marking as Present", existingPackageId, currentInstallFeature.FeatureName));
                    //TODO: add logic to store state so that during Plan phase can set package and feature states based on this info
                } else {
                    Log(string.Format("Migrating feature {1} of Package {0} - marking as Absent", existingPackageId, currentInstallFeature.FeatureName));
                    //TODO: add logic to store state so that during Plan phase can set package and feature states based on this info
                }
            }
        }
    }
}

DetectMsiFeature 告诉您新包的功能状态；它没有安装，所以显然这些功能没有。 DetectRelatedMsiPackage 为您提供使用（本机）MSI API 函数 MsiEnumFeatures 和 MsiGetFeatureState/MsiGetFeatureUsage 查询已安装版本的功能状态所需的数据。
