This module provides an observable dictionary implementation for managing application settings. The SettingsCollection<TKey, TItem> class wraps a standard Dictionary<TKey, TItem> and raises events when items are added, removed, modified, or when the collection is cleared. This enables consumers to react to configuration changes in real-time. The module exists to provide change-notification semantics for settings management, allowing dependent components to synchronize state when settings are mutated.
2. Public Interface
