System.Threading.Lock: The Purpose-Built Lock That Replaces Your object Hack
Since .NET 9, the System.Threading.Lock type gives you a dedicated, faster, and semantically clearer alternative to locking on a bare object. Here is how it works, why it is roughly 25% faster than Monitor, and what to watch out for when migrating.
