can't update or install any nuget packages in vs 2017

Reihaneh Khaksaran

I just installed vs 2017 and wanted to run my project but i'm facing so many warning and errors so I realized I should update my xamarin.android nuget packages but I keep getting this error message below:

Severity    Code    Description Project File    Line    Suppression State Error     Could not install package 'Xamarin.Android.Support.Animated.Vector.Drawable 27.0.2-preview1'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v8.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.           0

Repairing vs didn't work; deleting nuget.config didn't work; I even changed the version in .csproj file, but when i load the project it goes back to v8.0.

Can anybody please help?

Just as Jon said, the latest nuget package Xamarin.Android.Support.Animated.Vector.Drawable 27.0.2-preview1, which requires MonoAndroid81 at minimum to install.

However, only the latest Preview (15.6 Preview 2) version of Visual Studio includes Android 8.1 support. As this moment, current release version is 15.5.4, preview release version is 15.6 Preview 2. So if you want use that nuget package the latest version 27.0.2-preview1, you need download the latest version of Visual Studio 15.6 Preview 2 and install Android SDK 8.1.

If switch to Visual Studio 15.6 Preview 2 is not your choice, you should not update that package to the latest version, just use the version 26.1.0.1.

Hope this answer more clear.
