Affected platform version

.NET 6 / .NET 7

Description

Hello,
Are you supporting MAUI?
I added nuget package: Xamarin.AndroidX.Core.SplashScreen to maui boilerpate from VS 17.6.4 and I got issues like that:

I have tried with package versions: 1.0.1.1 (latest) and 1.0.0.3. and latest versions of sdks .NET 6 and 7.

Do you any workaround for that issue?

Steps to Reproduce

Create new project using ".NET MAUI App" template.
Install latest Xamarin.AndroidX.Core.SplashScreen to your just created project.
Try to build

Did you find any workaround?

Not so far

Thanks for the feedback.

I cannot repro on net8.0-android preview.

@sowacx

Thanks a lot. I created my sample and was able to reproduce, but this sample of yours was helpful to compare the csproj files.

Cannot upload sample.

Seems like transitive dependencies depend on

kotlin-stdlib 1.7.20.1 (9 months)

https://www.nuget.org/packages/Xamarin.Kotlin.StdLib/1.7.20.1

and
kotlin-stdlib 1.8.0.1 (6 months)

https://www.nuget.org/packages/Xamarin.Kotlin.StdLib/1.8.0.1
kotlin-stdlib 1.8.20.1 (2 months - after alignment bumps)

https://www.nuget.org/packages/Xamarin.Kotlin.StdLib/1.8.20.1

Investigating further: moved types between maven packages.

Attempt to explicitly define kotlin package reference with version 1.8.21.1

Hey @moljac,
I was testing on two machines, first one is win11-x64 and workload list for that machine is:

Second one for mac-arm:

Hey @moljac In related issues people are suggesting some workaround like adding such package to proj:
<PackageReference Include="Xamarin.Kotlin.StdLib.Jdk8" Version="1.8.0" />
I played with that, but without success. Do you know any potential workaround for that now?
I checked also lately released version of Xamarin.AndroidX.Core.SplashScreen (1.0.1.2), but same issue still appears.

Can you please post all packageReferences, please?

Hey @moljac In related issues people are suggesting some workaround like adding such package to proj:

Yes, explicit PackageReferences help in general, but there are also cases where it does not help.

I played with that, but without success. Do you know any potential workaround for that now?

Not yet. I need to examine dependency tree/forest.

This worked for me in previously attached sample (net6.0 and net7.0):

		<PackageReference Include="Xamarin.AndroidX.Core.SplashScreen" Version="1.0.1.2" />
		<PackageReference Include="Xamarin.Kotlin.StdLib.Jdk8" Version="1.9.0.1" />

I will add newer sample tomorrow.

I checked also lately released version of Xamarin.AndroidX.Core.SplashScreen (1.0.1.2), but same issue still appears.

I linked those two packages as you wrote and looks that is building fine!
