GalaSoft.MvvmLight Package 参考错误与 .net 标准 2.0 项目

Question

Hi Stackoverflow community,

I am in the process of creating a.Net Standard 2.0 Library project for my Xamarin Cross Platform App.

For the Droid project which references the above project I am getting the following error for one of the NuGet packages:

Can not resolve reference: 'GalaSoft.MvvmLight', referenced by 'NetStdLibProject'. Please add a NuGet package or assembly reference for 'GalaSoft.MvvmLight', or remove the reference to 'NetStdLibProject'.    NetProject.Droid

I have added following NuGet Packages to my NetStdLibProject project:

1. MVVMLight (5.4.1.1)

2. MVVMLightLibs (5.4.1.1) [This has following warning]

(Package 'MvvmLightLibs 5.4.1.1' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework '.NETStandard,Version=v2.0'. This package may not be fully compatible with your project.)

Please advise if there is a way to handle this scenario, or even if I am missing something. Also, please let me know if I need to include other related/beneficial packages.

PS: Me and my colleagues use Visual Studio 2019 (Windows & Mac both, Mac for IOS part to be somewhat specific)

Thanks for reading and any help is highly appreciated.

As Jason suggested in the comment, you should install MvvmLightLibsStd10 for .NET Standard :

You should uninstall the MvvmLightLibs package and install MvvmLightLibsStd10 for all projects (sharedPrject,Android.project,iOS.project).

Right click your solution (not single project) and choose Manage Nuget Package for solution .

see my updated screenshot:

Refer: mvvmlight
