WebSocket4Net cannot Nuget dependency to iOS proje

问题:

I am trying to install WebSocket4Net to my iOS/Android project in Xamarin.

When I add it to the Android project everything works great. When I try to add it to the iOS project I see this...

Install-Package : Could not install package 'WebSocket4Net 0.12'. You are trying to install this package into a project that targets 'Xamarin.iOS,Version=v1.0', 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.
At line:1 char:1
+ Install-Package WebSocket4Net
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

Am I on too old/too new of a project to add this perhaps?

You are currently working on a Unified iOS project, while the NuGet package does not contain such an assembly. Quite similarly an issue was documented,

Kerry has the Unified iOS support done already in code base,

So you either wait for an updated NuGet package, or simply use the source code directly.
