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?
