The RegisterProjectType method is called in SetSite method. In SetSite, the package creates its project factory and passes a pointer to the IVsProjectFactory interface to the environment by calling RegisterProjectType.

The environment uses the pointer to create projects from this project type using the CreateProject method.

The environment knows which package to load for a specific project type from the registry data.
