Features of projects include:

• A project collects together a set of files and folders.
• A project's location controls where the project's resources are stored in the local file system.
• A project's build spec controls how building is done on the project.
• A project can carry session and persistent properties.
• A project can be open or closed; a closed project is passive and has a minimal in-memory footprint.
• A project can carry references to other projects.
• A project can have one or more project natures.

This interface is not intended to be implemented by clients.

Projects implement the IAdaptable interface; extensions are managed by the platform's adapter manager.
