At this moment, the project contains three templates: Blank app template, Hub app template and Navigation app template.
The Blank app template is a project for a single-page Windows app that has no predefined controls or layout.
The Hub app template is a project for a three-page Windows app that uses a Hub control and dedicated pages display group and item details.
The Navigation app template is a project for a Windows app that has predefined controls for navigation.
To use, simply install the extension and you will have the three app projects in your TypeScript project templates definitions.
