Current .NET 9 is not properly compatible with Android binding libraries

[Kebechet]

Description

Many android binding libraries require at least: Xamarin.AndroidX.Lifecycle.LiveData version 2.8.7.1
but MAUI 9.0.22 requires older version >=2.8.5.1 && < 2.8.6 and because of this our Android binding fails to build.

The reason why .NET 8.0.100 works with this is because it's dependencies dont contain upper version limit. It requires just Xamarin.AndroidX.Lifecycle.LiveData version >2.6.1.3

Version conflict detected for Xamarin.AndroidX.Lifecycle.LiveData.Core. Install/reference Xamarin.AndroidX.Lifecycle.LiveData.Core 2.8.7.1 directly to project DemoApp to resolve this issue. 
 DemoApp -> Kebechet.Maui.RevenueCat.InAppBilling -> Kebechet.Maui.RevenueCat.Android 7.12.0.4 -> Xamarin.AndroidX.Fragment.Ktx 1.8.5.1 -> Xamarin.AndroidX.Fragment 1.8.5.1 -> Xamarin.AndroidX.Lifecycle.LiveData.Core (>= 2.8.7.1) 
 DemoApp -> Microsoft.Maui.Controls 9.0.22 -> Microsoft.Maui.Controls.Core 9.0.22 -> Microsoft.Maui.Core 9.0.22 -> Xamarin.AndroidX.Lifecycle.LiveData 2.8.5.1 -> Xamarin.AndroidX.Lifecycle.LiveData.Core (>= 2.8.5.1 && < 2.8.6).

Steps to Reproduce

1. Download branch _net9-compatability https://github.com/Kebechet/Maui.RevenueCat.InAppBilling/tree/_net9-compatability
2. Try to build demo/DemoApp/DemoApp.sln
3. You will get the error I mentioned above because of dependency incompatabilities

[Marnie-Majait]

This issue has been verified Visual Studio 17.13 Preview 2.1 (9.0.22 & 9.0.21 & 9.0.0). Can repro this issue on android platform. 8.0.100 works fine.

[moljac]

.NET 9 is properly compatible with Android libraries, but .NET 9 is stricter with dependencies (transitive)

If you add:

    <PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData.Core" Version="2.8.7.1" />
    <PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData.Core.Ktx" Version="2.8.7.1" />

You will get new set of errors

Those errors are known and described in

Something is using (as transitive dependency) Binding.Intercom.Kotlinx.Serialization.* which is not officially supported bindings.

Thank you for the info. I resolved it in:
Kebechet/Maui.RevenueCat.InAppBilling@7243bf9

and everything works as expected
