What's the difference between the .NET Framework SDK and the Targeting pack : <p>I'm trying to install the .NET Framework 4.7.1 in Visual Studio and I'm given the choice to install:</p>

<ul>
<li>.NET Framework 4.7.1 SDK</li>
<li>.NET Framework 4.7.1 targeting pack</li>
</ul>

<p>Do I need them both? What's the difference between each of them?</p>
