Unable to publish .net8-android App 'Microsoft.Android.Runtime.34.android-arm64 was not downloaded' (after Release of .NET9)

[monsterkeks]

Android framework version

net8.0-android

Affected platform version

.NET8.0.100

Description

We're currently facing a broken GH-Actions Release-Pipeline with our .NET8-Android-App. The output of the install of the workload looks like this:

so we're only seeing Microsoft.Android.Runtime.35.android-xxx are installed. The dotnet publish looks like this (with ENVIRONMENT BUILD_TOOLS_VERSIONto34.0.0``):

dotnet publish 'src/ArieTech.MedSR.Client.App/ArieTech.MedSR.Client.App.csproj' -c Release -f net8.0-android --no-restore /p:RuntimeIdentifier=android-arm64 /p:AndroidPackageFormat=aab /p:ApplicationVersion='60' /p:ApplicationDisplayVersion='0.8.1.60'

which results in the following error (Microsoft.Android.Runtime.34.android-arm64 was not downloaded):

Error: C:\Program Files\dotnet\sdk\9.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(495,5): error NETSDK1112: The runtime pack for Microsoft.Android.Runtime.34.android-arm64 was not downloaded. Try running a NuGet restore with the RuntimeIdentifier 'android-arm64'. [D:\a\med.SR\med.SR\src\ArieTech.MedSR.Client.App\ArieTech.MedSR.Client.App.csproj::TargetFramework=net8.0-android]
Error: Process completed with exit code 1.
##[debug]Finishing: Publish

Steps to Reproduce

1. Create new .NET8 based Maui App
2. Use <PackageReference Include="Microsoft.Maui.Controls" Version="8.0.100" />
3. Set <TargetFrameworks>net8.0-android</TargetFrameworks>
4. Setup a GH-Actions Pipeline with yml like:

    - name: Install MAUI workload
      run: dotnet workload install maui-android

    - name: Publish
      run: dotnet publish 'src/YourFolder/YourApp.csproj' -c Release -f net8.0-android --no-restore /p:RuntimeIdentifier=android-arm64 /p:AndroidPackageFormat=aab /p:ApplicationVersion='${{github.run_number}}' /p:ApplicationDisplayVersion='${{ env.MAJOR }}.${{ env.MINOR }}.${{ env.PATCH }}.${{github.run_number}}'

Did you find any workaround?

No.
We fought for about whole working day to find a workaround for creating a new release of our .NET8-based Android-App. Things we tried:

• Changed dotnet workload install maui-android to dotnet install maui-android --version 8.0.402
• Changed TargetFramework to net8.0-android35.0
• Changed ENVIRONMENT BUILD_TOOLS_VERSION to 35.0.0
