Issue while updating android target version to 33 in Xamarin

parixita sakhiya 0

I have to update android target version to 33 so trying to run my project in VS 2022 then it gives below error while in VS 2019 worked fine with android target version 28.

The imported project "/usr/local/share/dotnet/x64/sdk/6.0.414/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets" was not found. Confirm that the expression in the Import declaration "/usr/local/share/dotnet/x64/sdk/6.0.414/Microsoft/Portable/v4.5/Microsoft.Portable.CSharp.targets" is correct, and that the file exists on disk. (MSB4019)

For further investigation, could you please provide the following information?

What is your specific version number for VS 2022?

Could you please provide detailed steps to reproduce this issue?

Did you try cleaning up the bin and obj folders in the solution?

Your prompt reply will be highly appreciated.

Till now i'm running my project in VS 2019 and now to upgrade android target framwork version to 33 i have to run my project in VS 2022 so i simply open my project in VS 2022 and Rebuild it again and it gives me error for Microsoft.Portable.CSharp.targets. If i run same project in VS 2019 then it's working properly. Above error is only for VS 2022

In Visual Studio 2022, PCL is not used as the default installation.

Portable Class Library (PCL) project templates are no longer available, and project support will not be installed by default. New projects intended to target multiple platforms should use the .NET Standard project type. Customers who require PCL project support must install the component separately from the Individual Components tab in the Visual Studio installer.

Therefore, you need to open Visual Studio Installer, check .NET Portable Library Targeting pack in .NET desktop development.

Thanks for your feedback.

According to the official documentation of the PCL, it has been deprecated in the latest version of Visual Studio.

Portable Class Libraries (PCLs) are considered deprecated in the latest versions of Visual Studio. While you can still open, edit, and compile PCLs, for new projects it is recommended to use .NET Standard libraries to access a larger API surface area.

In addition, for Visual Studio component issues, it is recommended that you post this issue to Visual Studio Feedback.

Going from 28 to 33 is quite a jump. i.e. Android 9 to Android 13. My advice would be to start again making a new project based on the old functionality using VS2022 Community Edition 17.7.4. If it is just Android then I'd suggest starting your new app based on Android's Navigation Component (Google's recommendation for modern Android development), which is basically a single activity with multiple fragments for each new screen. The Navigation Component as its name implies supplies the navigation.

I've several tutorials (sample projects) on my GitHub page which should get you going in the right direction.

You've also got to consider that Xamarin.Android development is now finished - it will be maintained till the middle of next year, so to move to Android 14 you will need a conversion path to Net7 and then Net8 (Release Candidate 1 has just been released (VS2022 17.8.0 Preview 2.0.)
