我正在使用WiX 3.7的Burn / Managed Bootstrapper应用程序功能来创建基于MBA的自定义安装程序。对于我的捆绑软件链中的每个软件包，在执行MinorUpdate时，我可以轻松检测已安装哪些软件包功能，以确保在升级期间通过使用WiX基类中为引导程序提供的这些事件来保留这些功能选择：DetectPackageComplete，DetectMsiFeature，DetectRelatedBundle，DetectRelatedMsiPackage，DetectComplete。
但是，在MajorUpgrade期间，我只看到了一种方法来确定安装了哪些软件包，但我没有看到如何确定安装了哪些功能，因为DetectMsiFeature事件不会触发。< / strong>我尝试在产品的配置上使用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？

注意：如果有帮助，我可以提供一个包含所有代码的完整工作的VS解决方案。

我正在标记Bob Arnson's response作为答案，因为它给了我推动这一点所需要的东西，但对于遇到这篇文章的其他人，我想我会更详细地介绍一下你是怎么回事可以使用WiX提供的ProductInstallation类（位于WiX SDK中的Microsoft.Deployment.WindowsInstaller.dll程序集中）收集功能状态，从而无需直接调用本机MSI API。
以下是可以注册到DetectRelatedMsiPackage事件的方法示例。请注意，您需要存储您收集的信息，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，所以显然功能不是。 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。
