How to use AddOptionalPackageAsync?

Can you try add the second package under optional packages as well in your AppInstaller file something like this:

 <OptionalPackages>
        <Bundle
            Name="Julia-1.4.1"
            Publisher="CN=Julialang"
            Version="1.0.0.0"
            Uri="https://winjulia.s3-us-west-1.amazonaws.com/Julia-1.4.1.appxbundle" />
        <Bundle
            Name="Julia-1.4.2"
            Publisher="CN=Julialang"
            Version="1.0.0.0"
            Uri="https://winjulia.s3-us-west-1.amazonaws.com/Julia-1.4.2.appxbundle" />
 </OptionalPackages>

That should install both packages, or is that not your desired workflow?

As another install option from your code, consider using AddPackageByAppInstallerFileAsync to install packages defined in your AppInstaller file. You can find other AppInstaller file APIs here.

About using AddOptionalPackageAsync from code, can you try a few things:

Add the packagemanagement capability to your app doing performing the install.

<Package>
...

  <Capabilities>
    <rescap:Capability Name="packageManagement" />
  </Capabilities>
  
...
</Package>

Use the packagefamilyname when calling AddOptionalPackageAsync - you can get the specific package's packagefamilyname by running Get-AppxPackage when it's installed on a machine. So you'd have to install it and run the command to get the correct value for future use. There's an explanation here
Make sure your packages are part of a related set.

Cheers,

Tanaka_Jimha Thanks! I tried all your suggestions, but no luck so far. Here are some more details:

I don't want to install all the optional dependencies at the same time when the main app is installed, so I don't think I should add all of them to the <OptionalPackages> element in the appinstaller file, right? I only want one of them installed with the main app, so I add that optional package to the <OptionalPackages> element, and then all the other optional packages I want to be able to install via an in-app option, so I add all of those packages to the <RelatedPackages> element in the appinstaller file. You can see the details of how I do this in the code that I posted with the original message.

I think https://docs.microsoft.com/en-us/uwp/api/windows.management.deployment.packagemanager.addpackagebyappinstallerfileasync?view=winrt-19041 for the same reason is also not the right tool to implement my in-app feature add thing, right? As far as I can tell, it doesn't provide an option to install a specific optional package of the app, right? Or did I miss an option there somewhere?

I did add <rescap:Capability Name="packageManagement" /> to my main app now, and it shows up in the UI when I install that, but it doesn't change the error message I get.

When I install all the optional packages on my system, and then run the following ps code:

> $x = Get-AppxPackage Julia*
> $x.Dependencies

I get this output:

Name              : Julia-1.4.1
Publisher         : CN=Julialang
Architecture      : X64
ResourceId        :
Version           : 1.0.0.0
PackageFullName   : Julia-1.4.1_1.0.0.0_x64__87dh6scs60qg2
InstallLocation   : C:\Program Files\WindowsApps\Julia-1.4.1_1.0.0.0_x64__87dh6scs60qg2
IsFramework       : False
PackageFamilyName : Julia-1.4.1_87dh6scs60qg2
PublisherId       : 87dh6scs60qg2
IsResourcePackage : False
IsBundle          : False
IsDevelopmentMode : False
NonRemovable      : False
IsPartiallyStaged : False
SignatureKind     : Developer
Status            : Ok

Name              : Julia-1.4.2
Publisher         : CN=Julialang
Architecture      : X64
ResourceId        :
Version           : 1.0.0.0
PackageFullName   : Julia-1.4.2_1.0.0.0_x64__87dh6scs60qg2
InstallLocation   : C:\Program Files\WindowsApps\Julia-1.4.2_1.0.0.0_x64__87dh6scs60qg2
IsFramework       : False
PackageFamilyName : Julia-1.4.2_87dh6scs60qg2
PublisherId       : 87dh6scs60qg2
IsResourcePackage : False
IsBundle          : False
IsDevelopmentMode : False
NonRemovable      : False
IsPartiallyStaged : False
SignatureKind     : Developer
Status            : Ok

So from this I take it that I should use "Julia-1.4.2_87dh6scs60qg2" as the string that I pass to AddOptionalPackageAsync? I'm doing that now, but I still get the same error message "Access is denied".

I do think everything is in one related set, I'm creating all the packages with a PackagingLayout.xml file that looks like this:

<PackagingLayout xmlns="http://schemas.microsoft.com/appx/makeappx/2017">
  <!-- Main game -->
  <PackageFamily ID="Julia" FlatBundle="true" ManifestPath="appxmanifest.xml" ResourceManager="false">
    
    <!-- x64 code package-->
    <Package ID="Julia-x64" ProcessorArchitecture="x64">
      <Files>
        <File DestinationPath="Julia\Julia.exe" SourcePath="C:\Users\david\source\repos\WinJulia\Release\Julia.exe"/>
        <File DestinationPath="Images\*.png" SourcePath="Images\*.png"/>
      </Files>
    </Package>

    
  </PackageFamily>

  <PackageFamily ID="Julia-1.4.2" Optional="true" ManifestPath="juliaversions\julia-1.4.2-appxmanifest.xml" ResourceManager="false">
    <Package ID="Julia-1.4.2.x64" ProcessorArchitecture="x64">
      <Files>
        <File DestinationPath="Julia\**" SourcePath="C:\Users\david\source\repos\WinJulia\optionalpackages\julia-1.4.2\Julia\**"/>
        <File DestinationPath="Images\*.png" SourcePath="Images\*.png"/>
      </Files>
    </Package>
  </PackageFamily>

  <PackageFamily ID="Julia-1.4.1" Optional="true" ManifestPath="juliaversions\julia-1.4.1-appxmanifest.xml" ResourceManager="false">
    <Package ID="Julia-1.4.1.x64" ProcessorArchitecture="x64">
      <Files>
        <File DestinationPath="Julia\**" SourcePath="C:\Users\david\source\repos\WinJulia\optionalpackages\julia-1.4.1\Julia\**"/>
        <File DestinationPath="Images\*.png" SourcePath="Images\*.png"/>
      </Files>
    </Package>
  </PackageFamily>

  <PackageFamily ID="Julia-1.4.0" Optional="true" ManifestPath="juliaversions\julia-1.4.0-appxmanifest.xml" ResourceManager="false">
    <Package ID="Julia-1.4.0.x64" ProcessorArchitecture="x64">
      <Files>
        <File DestinationPath="Julia\**" SourcePath="C:\Users\david\source\repos\WinJulia\optionalpackages\julia-1.4.0\Julia\**"/>
        <File DestinationPath="Images\*.png" SourcePath="Images\*.png"/>
      </Files>
    </Package>
  </PackageFamily>
</PackagingLayout>

And I believe that should create all packages as being in one related set, right?

Hi davidanthoff

Access Denied means you're having permission issues calling the API. Our devs said the fastest way to root cause will be to get logs. Can you please make a Feedback Hub submission capturing the error in the Developer Platform > App Deployment category:

After capturing the issue, can you also attach the appxmanifest.xml files of your main app and optional packages with the submission. Please send me a link to the issue once you're done.

Thanks,

Tanaka

  Tanaka_Jimha Here is the link https://aka.ms/AA8obl4, hope that helps.
  
  I'm also preparing a GitHub repo with all the code that I use to create these msix packages, it is all open source, so no problem to share that.
