To get started using these Windows 8 Visual Studio 2012 TypeScript templates you will first need to install the TypeScript plug-in for Visual Studio 2012. Currently these templates have been tested under TypeScript 0.8.1.1 only and the generated .jsproj files have this path hard-coded in.

Once the files are there, shutdown all instances of Visual Studio 2012 and execute “devenv.exe /InstallVSTemplates” as admin. If you have multiple copies of Visual Studio installed, make sure you’re executing the one for VS2012.
Once you’ve completed those steps successfully, you should see three new TypeScript-based templates as shown in the very first figure of his blog post.
