Create an AsyncExclusiveLock instance and call AcquireAsync with a CancellationToken, which returns a ValueTask without blocking the caller thread. Release the lock in a finally block, and optionally use AcquireAsync with a TimeSpan to get a TimeoutException on failure.

AsyncMulticastSequence<T> is a single-producer, multi-consumer async broadcast channel implementing IAsyncEnumerable<T>. The producer calls WriteAsync and TryComplete, while each consumer creates its own enumerator via await foreach to receive all events.

No, blocking locks like Monitor or Lock and DotNext async locks are unaware of each other and must not be mixed on the same object. SemaphoreSlim is the one exception, supporting both blocking and async acquisition through Lock.Semaphore and AsyncLock.Semaphore facades.

No, DotNext async locks are non-reentrant, so recursive acquisition causes a deadlock that is difficult to diagnose. Always structure code so a lock is acquired only once per logical operation.

The repository pins DotNext 6.6.0 and DotNext.Threading 6.6.0 in Directory.Packages.props, both compatible with .NET 10. Version changes require an explicit Directory.Packages.props update.

Use AsyncMulticastSequence when multiple consumers must each receive every event from a single producer. For a single-consumer pipeline, a plain Channel<T> remains the simpler and preferred shape.
