Example for powershell extension

[cz-dev-ge]

Hi there,

I am upgrading a WiX3 project to WiX 4. My wxs contains the old http://schemas.gardiner.net.au/PowerShellWixExtensionSchema and a script like this:

<powershell:Script Id="MyScript" Elevated="yes">
  <![CDATA[echo Hello World!]]>
</powershell:Script>

This is not available in WiX4. But there is http://wixtoolset.org/schemas/v4/wxs/powershell.

Unfortunately I could not find any examples on how to use it. Could someone please provide one?

Best regards.

PowerShell docs are here. It is designed to install (old) PowerShell stuff. Not sure it is even useful in modern PowerShell.

Thanks. Whats the intended way to call scripts?

There is no such intention in the Windows Installer nor WiX itself today. If you must write a custom action, I personally recommend writing data-driven custom actions that integrate with the Windows Installer transaction to ensure proper install, uninstall, upgrade, and patch behavior with rollback for each.

Thank you. I'll give that a shot.
