Unity projects (a folder with Assets and ProjectSettings/ProjectVersion.txt)
are detected without a generated solution: Assets / Packages become source
roots, ProjectSettings resources, and Unity's cache and build folders are
excluded before they exist. A Unity pane in the Project view shows the
editor version and hides .meta files, generated C# project files and
caches (each can be shown again).
Operations on assets under Assets keep their .meta files consistent:
rename and move carry the metadata (same GUID), delete removes both, copy
generates new GUIDs and updates references inside the copied group, and
file-move undo and workspace edits include the metadata. Destination
metadata conflicts and links inside the project are rejected before
anything changes.
