Now for the category wrapper you can simply map each category to a SemaphoreSlim that you await to ensure that all operations within a category are serialized and then just use our existing TaskQueue to ensure that no more than N of these operations are running in parallel. Other than that it's mostly just various overloads to support different

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. I'm still not sure if this is the right approach: 2015-08-17 I did swap _isDisposed=true and _semaphore.Release() around in its Dispose though in case it somehow got called multiple times. Also it is important to note SemaphoreSlim is not a reentrant lock, meaning if the same thread calls WaitAsync multiple times the count the semaphore has is decremented every time. In short SemaphoreSlim is not Thread I love that .NET has so many useful utilities available in the base framework.

Dispose ();}} It also provides methods EnterUpgradeableReadLock and ExitUpgradeableReadLock to upgrade a reader lock to writer, and bring back avoiding possible deadlocks. SemaphoreSlim is a lightweight version, for using within a single process. It also supports cancellation tokens and async wait. The initial value of the CurrentCount property is set by the call to the SemaphoreSlim class constructor.

Perry using a concept whereby one protects access to a shared resource using a critical section in a way that works comfortably with the new await/async keywords. Protecting shared resources like files is a little more subtle now that asynchronous is so easy. The Dispose method leaves the SemaphoreSlim in an unusable state.
