How to: Add Templates to the New Project Dialog Box
A number of predefined project templates are installed during Visual Studio installation. For a complete list of predefined project templates, see Creating Projects from Templates. In addition to default project templates you can create custom or subtype-specific project templates. For example, the Smart Device subtype provides its own templates for Visual C# and Visual Basic projects. For instructions on how to create a custom template, see How to: Create Project Templates.
To add a template to the New Project dialog box
Create a template, including the MyTemplate.vstemplate file.
Select the files in your template (including the .vstemplate file), right-click them, click Send To, and then click Compressed (zipped) Folder. The files that you previously extracted are compressed into a .zip file.
Put the .zip template file in %USERPROFILE%\Documents\Visual Studio 2013\Templates\ProjectTemplates.
