AsyncSemaphore 1.0.2

AsyncSemaphore

A simple wrapper around a SemaphoreSlim that supports automatic releasing of a lock on scope exit with the using keyword.

No more try/finally code blocks!

Usage:

private readonly AsyncSemaphore _asyncSemaphore = new AsyncSemaphore(1, 1);

public async Task MyMethod()
{
    // Just assign the `IDisposable` returned from `WaitAsync` to a variable and use the using statement with it
    using var lockHandle = await semaphore.WaitAsync();

    // Do whatever you want - Even if we throw exceptions, we'll release the semaphore once we leave this method's scope
    await DoSomething();
}
