It may use a ManualResetEvent that uses a SafeWaitHandle which is a SafeHandle and it has an unmanaged handle. You can see it in SafeHandle is finalizable so if you don't dispose of it (by disposing of the SemaphoreSlim) it will go to the finalizer that will need to do that for you. SemaphoreSlim doesn’t implement IAsyncDisposable, so all this does is use up another thread pool thread to run the Dispose.. Derived Classes.

By voting up you can indicate which examples are most useful and appropriate. This stems from the problem where I wanted to dispose of my class containing the SemaphoreSlim instance, and was unsure how to safely and elegantly deal with the SemaphoreSlim instance as well.

The Dispose method leaves the SemaphoreSlim in an unusable state. After calling Dispose, you must release all references to the SemaphoreSlim so the garbage collector can reclaim the memory that the SemaphoreSlim was occupying. SafeHandle is finalizable so if you don't dispose of it (by disposing of the SemaphoreSlim) it will go to the finalizer that will need to do that for you. Since the finalizer is a single thread it may get overworked in certain situations so it's always advisable to dispose finalizable objects.

With async/await becoming more and more prevalent in modern code so has the need for async synchronization constructs. Unlike their synchronous counterparts (e.g. Monitor, Mutex, ReaderWriterLock, etc.) .NET doesn’t offer almost any built-in asynchronous synchronization constructs, but it does contain the basic building blocks to build them on your own (mainly Task, TaskCompletionSource WaitUntilCountOrTimeoutAsync(TaskNode asyncWaiter, int millisecondsTimeout, CancellationToken cancellationToken) { // Wait until either the task is completed, timeout occurs, or cancellation is requested.
