i'm trying to install "Install-Package Xamarin.Android.Support.Design" into Xamarin Visual Studio 2015, but after it starts downloading, this error occurs
Install-Package : Unable to find package 'Xamarin.Android.Support.Design' At line:1 char:1 + Install-Package Xamarin.Android.Support.Design + CategoryInfo : NotSpecified: (:) [Install-Package], Exception + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PackageManagement.PowerShellCmdlets.InstallPackageCommand
i don't understand any of that, what is wrong?
