If you have already installed the TypeScript 2.03 plugin, and still don't see what you want, you may need the NodeJS tools for Visual Studio, Version 1.02 (or later) from https://www.visualstudio.com/vs/node-js/.
The TypeScript starters I use are under Project/Add New Item dialog Installed/NodeJS. You probably need to be in a NodeJS project to get these to work.

command.
Hopefully this helps.
