How to use T4 with VS2015? (Microsoft.TextTemplating.targets file not found)

Question

I just tried to open one of my projects with Visual Studio 2015 the first time, and it says:

The importede project "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\TextTemplating\Microsoft.TextTemplating.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

The files do not exist on disk indeed. What kind of SDK do I have to install in order to use text templating with VS 2015?

Answer 1

I have found the answer myself. One has to install the "Modeling SDK for Visual Studio", available here.
