安装后如何执行Wix自定义操作？

Question

I am using Wix3 to install WCF service to IIS.

How can I use my custom action (c#) function after installation completed? ie I need to open installed web.config file and replace hostname with real one.

Any ideas?

Answer 1

您可以在InstallExecuteSequence中的 InstallFinalize操作之后安排它。

Answer 2

There is a sequence of Actions in Windows Installer. The WiX tutorial has a good section on events (and is a great resource anyway).

A typical example of getting something to run after InstallFinalize is to get the installed app to start.

<InstallExecuteSequence>
   <Custom Action='LaunchFile' After='InstallFinalize'>NOT Installed</Custom>
</InstallExecuteSequence>

Answer 3

Why would you:

1) Need a custom action? 2) Do it after the install instead of during the install?

WiX has a built-in extension for handling what you are trying to do:

XmlFile Element (Util Extension)

It will update your XML after the file has been installed and handle rollback scenarios as well.

What you will have to write a CA for though is reading the XML value back into a property ti handle repair and upgrade situations. Read:
