Building wix bundle overwrites package

Question

Overview:

I am making an installer for a web app build on asp.net 8. I started with just doing an msi installer (Package) with a custom UI. I then wanted to also include the installers for the dotnet runtime and server hosting and quickly learned, that i cannot run other installers during my installation. So i made a additional project to make a bundle. This bundle now has the executables for the dotnet stuff and my own msi included in its chain.

The Problem:

I am building my web app package using a build script that i run with msbuild.

msbuild -p:PackageVersion=1.0.0;ProductCode={GUID Here} -t:BuildPackage;BuildBundle setup.build

I am doing it like this to automate the process of updating the installer when changes are made to the source code. I have other targets in setup.build, but they are irrelevant for my problem.

This is what the Targets look like.

 <Target Name="BuildPackage">
      <!--     At last create an installer -->
      <Message Text="TEST: @(WixCode)"/>
      <Exec
          Command='wix build -ext WixToolset.Iis.wixext -ext WixToolset.Netfx.wixext -ext WixToolset.Util.wixext -ext WixToolset.UI.wixext -d publishDir=$(Publish) -d Version=$(PackageVersion) -d ProductCode=$(ProductCode) -d MyWebResourceDir=. -o $(MsiOut) @(WixCode, &apos; &apos;)'
          ContinueOnError="false"
          WorkingDirectory="." />
      <!-- A message at the end -->
      <Message Text="Install package has been created." />

  </Target>    
      <Target Name="BuildBundle">
         <Exec
              Command='wix build -ext WixToolset.Util.wixext -ext WixToolset.BootstrapperApplications.wixext -d BundleVersion=$(BundleVersion) -d MyWebResourceDir=. -o $(BundleOut) @(BundleCode, &apos; &apos;)'
              ContinueOnError="false"
              WorkingDirectory="." />
      </Target>

Now, when i run this, the resulting Bundle.exe includes an msi installer that is not the one made with BuildPackage. When i run Bundle.exe it installs something, but it does not display my UI and when i check in my installed apps, i see my package but with the version number of the bundle not the package version. So i assume that when i build the bundle, it builds my package differently and adds it to the bundle, instead of the package that i specify.

This is the package group that i added in my bundle:

<Fragment>
    <PackageGroup Id="MainPackages">
        <PackageGroupRef Id="PrereqPackages" />
        <MsiPackage Id="WebApp" DisplayName="Installing Web App" SourceFile="path\to\App_Installer.msi" />          
    </PackageGroup>
</Fragment>

In my IDE i have excluded my package from the build in the configuration manager, so in theory it should be isolated from the build process of my solution. Although i don't build it in the first place, i wanted to mention it.

The Question:

I don't know how to prevent this and in generall have trouble understanding why it works like this.

I would appreciate any help and in the best case i would very much appreciate if anyone can explain to what goes on under the hood.

Thank you in Advance!

Answer 1

I apparently just had to switch from WixStandardBootstrapperApplication to WixInternalUIBootstrapperApplication. Now it shows the internal UI of my MSI package. It still uses the version number of the bundle when the msi package is installed, not the version specified in my msi package, but it does have all the functionality it is supposed to.
