Create a .NET 4.0 library from a PCL project where the code is identical

This is pretty annoying, I have a portable class library library (PCL) that had to abandon .NET 4.0 in the profile in order to access the correct API “on the PCL ground”. However, these APIs exist in .NET 4.0, so if the same code is in a .NET 4.0 project, it compiles just fine.

I need a minimal way to continue recompiling the code in this PCL project on .net 4.0, so I can include it in the Nuget package.

.csproj msbuild .net 4.0.

Build.proj:

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <ItemGroup> 
        <ProjectToBuild Include="MyPortableSolution.sln">

    </ItemGroup>
    <Target Name="Build">
        <MSBuild Projects="@(ProjectToBuild)"/>

MyPortableProj.csproj:
