Wizard Support for Nested Projects
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The IDE runs two wizards that the parent project for nested projects can implement: the New Project wizard and the Add Item wizard.
If a user starts the New Project wizard by selecting Add Project and clicking New Project on the File menu or by selecting Add and right-clicking New Project in Solution Explorer, the IDE runs the AddProject command and the parent project's implementation of the AddProject command either returns a template project file, or a wizard (.vsz) file that has a set of context parameters.
Similarly, a parent project's implementation of AddItem wizards returns a .vsz file that has a different set of context parameters.
For more information about wizards, see Wizard (.Vsz) File, Context Parameters and Registering Project and Item Templates.
