Much like the Components library, this library features base classes that handle things we've written a thousand times over, this time involving disposal. If you want to go with an implementation of the tried and true IDisposable, just inherit from SyncDisposable. Want a taste of the new IAsyncDisposable? Then, inherit from AsyncDisposable. Or, if you want to support both, there's Disposable. Each of these features abstract methods to actually do your disposal. But all of the base classes feature:

  • proper implementation of the finalizer and use of GC.SuppressFinalize
  • monitored access to disposal to ensure it can't happen twice
  • the ability to override or "cancel" disposal by returning false from the abstract methods (e.g. you're reference counting and only want to dispose when your counter reaches zero)
  • a protected ThrowIfDisposed method you can call to before doing anything that requires you haven't been disposed
  • an IsDisposed property the value (and change notifications) of which are handled for you

This library provides the IDisposalStatus interface, which defines the IsDisposed property and all the base classes implement it. This library also provides the INotifyDisposing, INotifyDisposed, and INotifyDisposalOverridden interfaces, which add events that notify of these occurrences.

Lastly, this library provides DisposableValuesCache and AsyncDisposableValuesCache, which each represents a cache of key-value pairs which, once disposed by all retrievers, are removed.
