Cannot find Microsoft.VisualStudio.TextTemplating assembly

Question

I have the Visual Studio SDK installed. Here is where the assembly is physically installed on my system:

C:\Program Files\Microsoft Visual Studio 2008 SDK\VisualStudioIntegration\Common\Assemblies\Microsoft.VisualStudio.TextTemplating.dll.

It does show up in the Add Reference dialog normally.

Visual Studio 2012 SDK folder is:

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VSSDK\VisualStudioIntegration\Common\Assemblies\v4.0

In the (new) GAC:

VS 2012 (v11.0)

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.TextTemplating.11.0\v4.0_11.0.0.0__b03f5f7f11d50a3a

VS 2013 (v12.0)

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.VisualStudio.TextTemplating.12.0\v4.0_12.0.0.0__b03f5f7f11d50a3a

These assemblies have been available for a while now as NuGet packages.

This allows for better dependency management via NuGet.
