Cannot Understand how to reference Shared Library Xamarin

I am getting started in the new release of Xamarin as seems allot more stable now for production in 2017 however I am facing an issue of understanding I have my web client calls in a shared library.

enter image description here

Which I want to reference in the standard forms master detail application template but when I go to right click on my forms app there is no add-reference so my question is how do I reference the FuelWc class in my Xamarin forms app.

This is my above project 

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Newtonsoft.Json" Version="11.0.2" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\FuelCallLogDLCore\FuelCallLogDLCore.csproj" />
  </ItemGroup>

</Project>

This code is the code which belongs to the main app of Xamarin forms where the views etc are held.

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <None Remove="appsettings.json" />
  </ItemGroup>

  <ItemGroup>
    <Content Include="appsettings.json">
      <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
    </Content>
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.0.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="2.0.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.0.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.2" />
    <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="2.0.1" />

  </ItemGroup>
    <ItemGroup>
   <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.2" />
</ItemGroup>
  <ItemGroup>
    <Reference Include="System">
      <HintPath>System</HintPath>
    </Reference>
  </ItemGroup>

</Project>

enter image description here

So my main question is: how the heck do I reference the code in the shared library?

Usually I would add reference then initiate the object using the standard 

Test1 _test = new Test1();

But because I cannot appear to ref the dll, I am at a loss.

There are three alternative methods for sharing code between cross-platform applications:

Shared Projects – Use the Shared Asset Project type to organize your source code, and use #if compiler directives as required to manage platform-specific requirements.

Portable Class Libraries – Create a Portable Class Library (PCL) targetting the platforms you wish to support, and use Interfaces to provide platform-specific functionality.

.NET Standard Libraries – .NET Standard projects work similarly to PCLs, requiring the use of Interfaces to inject platform-specific functionality.

Source: official documentation

I would highly recommend to get familiar with the differences between those methods, so you will be able to decide yourself what should work for your specific case.
