VS presents a “folder workspace” when opening a file system folder (directory) in VS.

A “multi-root workspace” can refer to multiple folders (directories) on different parts of the file system, and VS displays the contents of the workspace folder together in File Explorer. To learn more, see Multi-Root Workspaces.

In contrast to IDEs such as IntelliJ IDEA, NetBeans or Eclipse, the concept of a “Java project” is entirely provided by extensions, and is not the main concept in VS. If you work with “Java projects” in VS, you must install the necessary extensions to work with those project files.

For example, Maven, Eclipse, and Gradle Java projects are supported with Java™ Language Support by Red Hat, M2Eclipse, which provides support for Maven, and Buildship, which provides support for Gradle with the Eclipse JDT Language Server.
