Android application type

.NET Android (net7.0-android, net8.0-android, etc.)

Affected platform version

.NET 9

Description

Context: https://devdiv.visualstudio.com/DevDiv/_build/results?buildId=8749461&view=ms.vss-test-web.build-test-results-tab&runId=89641486&resultId=100000&paneView=attachments
Context: #8366

The MicrosoftIntune test fails in both Debug and Release mode with:

/Users/runner/.nuget/packages/microsoft.intune.maui.essentials.android/10.0.0-beta2/build/netstandard2.0/Microsoft.Intune.Maui.Essentials.android.targets(208,9): /Users/runner/work/1/s/bin/Release/dotnet/packs/Microsoft.NETCore.App.Runtime.Mono.android-x64/9.0.0-alpha.1.23577.7/runtimes/android-x64/native/libSystem.Security.Cryptography.Native.Android.jar doesn't contain /Users/runner/.nuget/packages/ and the mamified library won't be placed in the correct intune directory. This is not expected. [/Users/runner/work/1/a/TestRelease/11-30_21.20.10/temp/MicrosoftIntuneFalse/UnnamedProject.csproj]

Steps to Reproduce

Run the Intune test on .NET 9.

Did you find any workaround?

Will ignore this test for now.

    But wait, it's worse now: dotnet new android project with $(TargetFramework)=net9.0-android and the following additional NuGet packages:

      <ItemGroup>
    <PackageReference Include="Xamarin.AndroidX.AppCompat" Version="1.6.1.6" />
    <PackageReference Include="Microsoft.Intune.Maui.Essentials.android" Version="10.0.0" />
  </ItemGroup>

    Microsoft.Intune.Maui.Essentials.android v10.0 is the current latest version of the package.

    Build, and it immediately fails to build:

    $HOME/.nuget/packages/microsoft.intune.maui.essentials.android/10.0.0/build/netstandard2.0/Microsoft.Intune.Maui.Essentials.android.targets(159,9): error :
    Intune currently supports a maximum Xamarin.Android SDK major version of 34. Your major version is 35. Please downgrade your app's target framework.

    This check can be disabled by setting the $(IntuneValidateAndroidBuild) MSBuild property to false:

    dotnet build -v:diag -p:IntuneValidateAndroidBuild=false

    which then fails with the originally reported error:

    $HOME.nuget/packages/microsoft.intune.maui.essentials.android/10.0.0/build/netstandard2.0/Microsoft.Intune.Maui.Essentials.android.targets(208,9): error :
    …/dotnet/packs/Microsoft.NETCore.App.Runtime.Mono.android-arm/9.0.0-rc.1.24380.7/runtimes/android-arm/native/libSystem.Security.Cryptography.Native.Android.jar
    doesn't contain $HOME/.nuget/packages/ and the mamified library won't be placed in the correct intune directory.
    This is not expected.

    Any update on an expected release with support for .NET 9? Not long until .NET 10 will be out! @jonathanpeppers

    I'm not really sure who to ask about this, maybe file a ticket here?

    All I did here was write a test for their NuGet package, but they didn't add .NET 9 support as far as I can tell.

    We have the same issue. The Microsoft Intune works on .NET 8 Android, but we have a lot of issues regarding performance with some controls in my app. And some performance issues have been fixed on .NET 9.
    What time frame MAUI of Microsoft develop team have new version MAM Intune on .NET 9?

    Unfortunately not and I'm currently having some time off. I know we started conversations with the Intune team before I left. Hopefully that will get us somewhere!

    To be clear, the fixes are in the Microsoft.Intune.Maui.Essentials.android NuGet package.

    I'm not sure where the source code for it even lives? It must be a private repository somewhere.

    Unfortunately, downgrading to .NET 8 is no longer an option, as Google Play will require all app updates to target API level 35 starting August 31, 2025. Without API 35 support, we will not be able to publish any updates, which is a critical blocker for our release and long-term support.

    @alpayclsr1 no you can target API 35 in .NET 8 by using AndroidManifest.xml:

    <uses-sdk android:targetSdkVersion="35" />

    This will trigger a build warning, and you'd just ignore it.

    Ideally, you would upgrade to .NET 9, though.

    Thanks for the info, @jonathanpeppers . I’ll try target API 35 in the AndroidManifest.xml on .NET 8

    Are you kidding me? .NET 9 has been out for essentially a year now and .NET 10 is right around the corner. Intune is a Microsoft product. MAUI is a Microsoft product. HOW is this not supported! How frustrating to work on getting this all implemented only to find that I can't even implement MAM policies on the Android app with .NET 9 (which again, has been out almost a year in release build)

    @jfversluis do you have any news from MS Intune team?
    We're getting to Oct 31st, when API 35 will be required on PlayStore, that's a huge blocker for apps that uses Intune.
    I already posted an issue on their repo, but no response (microsoftconnect/ms-intune-app-sdk-android#301)

    The new version of the Intune package was released for .NET 9, if someone here was waiting for that:
