Compatibility and platform notes

Windows and POSIX filesystem behavior differs; several types have narrower lifecycle or encoding contracts. FileSystemWatcher is Linux/inotify-only at the pinned source.

Implementation-status evidence

The owning module contains 6 C++ test sources and participates in a physical component test executable. Source-file count is not a discovered-test count.

This page deliberately reports source and test topology instead of a hand-authored Done/Partial maturity badge. Consult limitations and subsystem documentation for material behavioral reductions.

Public header and entry inventory

This complete list is derived from modules/io/include. Each filename is a public discovery entry; it may declare more than one type, and it does not imply method-level .NET parity.
