Getting a "failed linking references" error when running an Android Project (Xamarin - Visual Studio 2022)

[BantiPlayz]

Android application type

Classic Xamarin.Android (MonoAndroid13.0, etc.)

Affected platform version

VS 2022

Description

I simply wanna test out this application: (https://github.com/bojibenji/Language-Learning-App-EZJapanese) on the android emulator but I keep getting several errors when doing so. I am new to Xamarin and C# Application development, but I just wanna experience running this specifically. So can anyone please show me the steps on how I can run this android application?

Steps to Reproduce

Solutions Attempted: Updating NuGet Packages, rebuilding solution, then I get error: "The $(TargetFrameworkVersion) for EasyJ.Android (v9.0) is less than the minimum required $(TargetFrameworkVersion) for Xamarin.Forms (10.0). You need to increase the $(TargetFrameworkVersion) for EasyJ.Android. ", I increased the TargetFrameworkVersion to 10.0, rebuild solution, back to the "failed linking references" and ocean of errors.

Did you find any workaround?

I don't have the old Classic Xamarin.Android installed anymore (it goes out of support soon) so its difficult to test.
My guess is that the NuGet packages will need upgrading if you want to up the TargetFramework to 10.0.

@dellis1972 I said I updated the NuGet packages though

[dellis1972]

So its likely then that those resouces have moved to another package as part of the update. I'm not sure which one though.

hi @BantiPlayz Did you have a solution for this

[yablos]

This one helped:

"Make sure you have TargetFrameworkVersion=v13.0 in your Droid.csproj"
Previously, there was = v10
And that was all + all your mentioned(delete bin,obj, nuget...)
