In VS2015, how do I create a Xamarin xaml forms project that uses .net standard?

Question

It's not obvious me how to incorporate .net core and .net standard into a blank xamarin xaml forms app. Can someone please step me through it?

Do this, start Visual Studio 2015, Create a Visual C# / Cross-Platform / Blank Xaml App (Xamarin.Forms Portable) project. Once that completes, integrate .Net Core and .Net Standard

Links on migrating from DNX to .NET Core CLI - https://learn.microsoft.com/en-us/dotnet/articles/core/migrating-from-dnx

After your upgrade a PCL to netstandard you will get a project.json such as this:

{
    "supports": {},
    "dependencies": {
    "Microsoft.NETCore.Portable.Compatibility": "1.0.1",
    "NETStandard.Library": "1.6.0"
},
"frameworks": {
    "netstandard1.4": {}
    }
}

Now, all we need to do is add a special “imports” flag and the PCLs we would like to consume under the netstandard profile

{
    "supports": {},
    "dependencies": {
    "Microsoft.NETCore.Portable.Compatibility": "1.0.1",
    "NETStandard.Library": "1.6.0"
  },
  "frameworks": {
    "netstandard1.4": {
      "imports": [
        "portable-net45+wp80+win8+wpa81"]
   }
  }
}

That little imports flag essentially tells NuGet that this package will totally work with PCLs that support this. Now you should be good to go to install any PCL NuGet that you would like:
