更新Wix3.11安装程序中的单个功能，而其他特性保持不变

Question

我一直在寻找解决这个问题的方法，但没有任何运气，所以我在这里问。

我有一个Wix3.11MSI安装程序来安装我的应用程序。我的应用程序有多个特性--应用程序(.NET Core )、数据库(PostgreSQL 12)、文档(PDF)。当有更新时，99%的时间只是应用程序中的更新。但是，如果用户在每次更新中重新安装所有功能，数据库中的松散数据就会被删除并再次创建。

是否有一种方法只影响在小/主要升级上选择的特性，还是我完全搞错了？

Answer 1

我可能已经想出了办法来做这个。WIX有一个叫做Boostrapper项目的东西，它可以接收多个安装项目(msi或exe文件)，并将它们全部安装在一个安装程序中。玩了一会儿之后，我注意到如果您部署了一个新版本的boostrapper安装程序，它有一些新版本的子安装程序和一些相同版本的子安装程序，那么只有新的版本才会被重新安装。

示例：

假设您有两个版本的引导程序安装程序，其中有以下的子安装程序版本：

Boostrapper安装程序1.0.0.0

1.0.0.0

• Database
• WPF应用程序安装程序1.0.0.0

Boostrapper安装1.0.1.0

1.0.1.0

• Database
• WPF应用程序安装程序1.0.0.0

如果您安装了引导程序安装程序1.0.0.0，那么引导程序安装程序1.0.1.0只会重新安装WPF应用程序，使数据库保持不变。
