如何使用 WiX Burn MBA 捆绑包在主要升级期间检测当前安装的功能？

我正在使用 WiX 3.7 的刻录/托管引导程序应用程序功能来创建基于 MBA 的自定义安装程序。对于我的捆绑包链中的每个软件包，在执行 MinorUpdate 时，我可以轻松检测到哪些软件包功能已安装，以确保在升级过程中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.

然而，在 MajorUpgrade 期间，我只看到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。我尝试使用MigrateFeatures产品配置上的标志，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主要升级时，检测/迁移现有功能的正确方法是什么？

我正在标记鲍勃·阿恩森的回应作为答案，因为它给了我推动这个过程所需的东西，但对于看到这篇文章的其他人，我想我会更详细地介绍如何使用 WiX 提供的收集功能状态ProductInstallation类（可在 WiX SDK 中的 Microsoft.Deployment.WindowsInstaller.dll 程序集中找到），从而无需自己直接调用本机 MSI API。

这是可以注册到的方法的示例DetectRelatedMsiPackage事件。请注意，您需要存储收集的信息，以便您可以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
                }
            }
        }
    }
