Mutually exclusive files in the same folder in a WIX Installer

问题

I would like to deploy mutually exclusive applications into mutually exclusive environments based on User Input in a WIX project. The research I've done tells me I can't do this using conditions http://www.joyofsetup.com/2007/05/30/feature-conditions-and-ui/ This seems like a fairly common question and a definitive best practice would be valuable.

I've implemented this using features and publishing events per the above article. The events in my UI are below.

In my situation I'm installing one of two mutually exclusive web applications into one of three different environments. I did this by creating 8 features, 1 each for the applications and all files except web.config and 6 for the web.config files depending on the application being installed and the environment being installed into. I had to include a condition in each of the features to pass ICE validation even though they are controlled by publish elements below because they are being installed to a directory named the same on different servers. Is there a better way or is this the standard practice for this sort of situation?

      <Publish Event="AddLocal" Value="WebApp"><![CDATA[ServerType="Web"]]></Publish>
      <Publish Event="Remove" Value="WebApp"><![CDATA[ServerType<>"Web"]]></Publish>
      <Publish Event="AddLocal" Value="DataApp"><![CDATA[ServerType="App"]]></Publish>
      <Publish Event="Remove" Value="DataApp"><![CDATA[ServerType<>"App"]]></Publish>
      <Publish Event="AddLocal" Value="WebDevConfigFeature"><![CDATA[ServerType="Web" AND Environment="Dev" ]]></Publish>
      <Publish Event="Remove" Value="WebDevConfigFeature"><![CDATA[ServerType<>"Web" OR Environment<>"Dev"]]></Publish>
      <Publish Event="AddLocal" Value="WebQAConfigFeature"><![CDATA[ServerType="Web" AND Environment="QA" ]]></Publish>
      <Publish Event="Remove" Value="WebQAConfigFeature"><![CDATA[ServerType<>"Web" OR Environment<>"QA"]]></Publish>
      <Publish Event="AddLocal" Value="WebProdConfigFeature"><![CDATA[ServerType="Web" AND Environment="Prod" ]]></Publish>
      <Publish Event="Remove" Value="WebProdConfigFeature"><![CDATA[ServerType<>"Web" OR Environment<>"Prod"]]></Publish>
      <Publish Event="AddLocal" Value="AppDevConfigFeature"><![CDATA[ServerType="App" AND Environment="Dev" ]]></Publish>
      <Publish Event="Remove" Value="AppDevConfigFeature"><![CDATA[ServerType<>"App" OR Environment<>"Dev"]]></Publish>
      <Publish Event="AddLocal" Value="AppQAConfigFeature"><![CDATA[ServerType="App" AND Environment="QA" ]]></Publish>
      <Publish Event="Remove" Value="AppQAConfigFeature"><![CDATA[ServerType<>"App" OR Environment<>"QA"]]></Publish>
      <Publish Event="AddLocal" Value="AppProdConfigFeature"><![CDATA[ServerType="App" AND Environment="Prod" ]]></Publish>
      <Publish Event="Remove" Value="AppProdConfigFeature"><![CDATA[ServerType<>"App" OR Environment<>"Prod"]]></Publish>
      <Publish Event="EndDialog" Value="Return">1</Publish>

The trick I like to do is have 2 components with 2 different key files

c1 -> f1 ( web.config.dev ) c2 -> f2 ( web.config.qa ) c3 -> f3 ( web.config.prod )

each of these files are then given a copy file element of web.config and a mutually exclusive condition

DEPLOYMENTTYPE~="DEV" DEPLOYMENTTYPE~="QA" DEPLOYMENTTYPE~="PROD"

The result is no more then 1 of these components will get installed. You might get a web.config.dev and a web.config and it'll work.

All of this can be done using a single feature.

Depending on whether you want to choose the files by environment (no questions), indirect user input (related question), or direct user input (feature selection), there are various approaches to take. Christopher Painter's approach is good for the first two, but for feature selection, you might try the technique described on this InstallTalk blog post.

Personally I would split the two separate applications out into two msi's with a common library for duplicated code. They can be bootstrapped together if required using burn.

Also there is no need to stored all the different versions of the web.config as the differing values can be modified at install-time using either the XmlFile or XmlConfig elements. The advantage of this method of modifying the web.config files is the values can also be passed into the installer on the command-line if they ever change, preventing the msi's from having to be rebuilt just for config changes. To make things easier you can even create dialogs to set them rather than passing them in via msiexec.
